About This Game

Retrovirus is a six degrees of freedom shooter which sends players into the depths of a computer on a search and destroy mission against an invasive virus. Retrovirus is being created by Cadenza Interactive, the indie studio behind the popular tower defense game Sol Survivor.

Players take command of an antivirus program, armed with the tools necessary to erase the virus’ very existence from the system. Movement and exploration are core to the gameplay, and players are encouraged to adapt to the demands of a world where free flight is the norm. Of course, the virus is armed to fight back, and first person shooter combat features heavily as players test their level of comfort with movement within the machine environment. Each player is able to customize their antivirus program with different plugins, allowing for a variety of approaches to a given situation.

The Retrovirus single player campaign focuses on the core story of the game, with the player’s goal being the eradication of the virus and the discovery of its origins. To defeat the virus, the player must solve puzzles, engage in dogfight-style combat, and explore the depths of the virtual world.

Retrovirus also features multi-player modes, designed to engage players’ social and competitive sides. Co-operative multi-player allows players to complete the campaign of the game with a friend, teaming up to restore the system to working order. Competitive multi-player will focus on the core of the six degrees of freedom shooter, hearkening back to the action-oriented shooters of the late 90’s and early 00’s.


  • Discover movement within a six degrees of freedom environment, free from the limits of traditional gravity-based environments.
  • Delve into a two-layered story, exploring the real-world origins of a malicious computer virus and cleansing the inner workings of the infected system.
  • Fight battles, complete puzzles and explore an environment built for the free-flying citizens of the computer system.
  • Customize an antivirus program, focusing on strength, speed or cunning, with weapons and utilities to suit a variety of play styles.
  • Join with a friend to remove the virus from the infected computer by playing the campaign in co-operative mode.
  • Compete against other players in a variety of multi-player modes, testing the limits of combat with six degrees of freedom.

Let me start with, I do not dislike this game. It isn't a great game, but it's not bad either. Gameplay reminds me of Descent(Never heard of it? Look it up!). The idea is you are an antivirus program inside of an infected computer. Of course the inside of the computer is designed to be like subways, and other tight rooms and corridors. I don't know why I can't get Wreck it Ralph out of my head but it can relate. Different programs are different characters. Anyway, the computer was infected with a worm so you have to work your way to finding it, killing stuff, and upgrading your definitions(abilities) to fight it.

So far there is a decent variety of weapons, enemies and challenges. You are introduced with more along your journey at a not very impressive rate. It does get repetative so I can only do about a level or two at a time. But that might just be me haha and I do not think I am very far in it so things can really pick up soon. I'll post updates as I play more or when I finish so check for comments before buying if you want to read any more crap I spew.

Okay, why were people expecting Descent? In D, you're in AN UNDERGROUND MINE. It's gonna be crampped and kinda confusing. A personal computer's busses are not gonna come anywhere near that, and it does become quite klausteric in some portions, emphasising quick judgement and 6DOF-CQC, like Descent. The graphics are supposed to be fancy to reflect modern computers, although I will say that the engine the game runs on is quite inefficent, but powerful nonetheless.

One of the only negative aspects I can find about this game is the AI, where they're just kinda point-and-shoot, and don't move around much or do anything special like Big D had. I also didn't like how the conductor has this OP hitscan weapon while infected, but when NOT infected, he's defenseless. Don't do that.

Okay, good elements: THE SOUNDTRACK. OH MY GOD THE SOUNDTRACK. It ain't D's techno shenanigans, but it fits the game damn fine, the synths come in warm and cold flavors and the boss themes are on-point, the neurofunk and Amen work is immaculate, and aranged OST is a standalone album - no question. Jonanthan Peros did a wonderful job composing and producing both the procedural and aranged work. I couldn't fathom how many bassbins would be destroyed if he ended up with a record deal on some label like Mindtech.

The story was grand. There were two layers: The good ol' fashion blow everything to Kingdom Come and save the babes, and then there was the email layer that told a deeper story for all those >muh immersion folks. I also like how the protag you play as actually IS a retrovirus. Able to function independantly through the system with no operating AV controller, change it's code on the fly, and then there's the Oracle's ability to forge definitions for unknown malware.
This level of AV tech simply does not exist yet. It is some next-level ♥♥♥♥. Most of the time, you have to have someone in meatspace to hand-scan lines and lines and lines of code before pushing it through with the next definitions update.
I also LOVE the little detail at the end where the only weapon that can hurt the final boss (which takes place in the BIOS, obviously) is the Interupt (shotgun). If you know anything about computers, you'd know why that is.

Lastly is the gameplay. It's a bit slow, but the open Steam Workshop allows for gameplay modifiers, and Big D's was actually fairly slow too, until you mastered chording and/or the AB (D2 and especially in D3 where pulsing it at 100% can accelerate you to breakneck speeds). Honestly I found it completely playable, but the framerate kinda made it hard, but I pushed through anyway beceause it was enjoyable. I also liked the upgrade system, while it didn't seem complete, it was very useful and I got a lot of use out of it - switching between abilities while under fire to fulfill a situation that my current loadout can't eat.
There was one bug that bugged me, and that was that rockets that hit walls don't hurt you, but if they hit a target, they do hurt you.
OH, and there are bugs that prevent you from 100% the whole game. But I got all the emails, so no biggie.

Overall, 8/10 would play again. In fact, I actually have played it twice. Oh, and I bought the album. It can be found here.

And before I get any downvotes or nasty comments, look at my icon (boss6's face), look at my current handle (bossrobotdad). I've been Going Down, Again! since 1995, and currently I've completed an Ace run (5.4mil points, all hostages, all ES missiles, all secret levels) and working on my Insane run. I like to come out of focus with the game to watch my own fingerwork on the keyboard because I'm amazed at how far I've come since '97/'98.
Do you think you can find a bigger Big D fanbwoy on this platform?
Don't answer that.

Buy? Likely. Retrovirus is a Six Degrees of Freedom (6DOF) FPS about a world within a person's computer, where a destructive worm has infected and corrupted the system. Your task as an agent of the anti-virus program is to of course, delete this worm. Emails scattered across the system, hints to the reasoning behind the worm attack.

6DOF essentially means freedom of moment, so you're constantly flying and have to deal with threats that can occur from any angle in 3D space. RV can't escape (and possibly doesn't want to) the comparison to Descent and Forsaken/Forsaken 64 - I think the developer refereneces Descent in forums.

Mecanics are based on weaponry and technology that use a limited, but regenerative resource called cycles that are displayed on your gun. You also have a scan function to highlight enemies, a charged scan to scan a wide area of enemies and to activate marks (bullet holes) made by your weapons. These marks vary depending on the weapon, such as a small explosion with the pistol-like Dual Strike, push back with the minigun style Thrash, or creation of gravity wells with the shotgun-like Interruptor, my personal favoritte. The use of cycles essentially means unlimited ammo, but requires you to manage shooting as you can easily run out if you shoot too much and you don't have any reload canisters. This is a problem with the larger hoard fights and some boss fights as there where times I felt I couldn't deal with the threat and I felt impossible with the Corrupted Driver boss battle (until I found a level exploit). You can also upgrade your "ship" and weaponry with bytes earned from killing enemies, destroying corruption and orange byte pickups which I think are called Memories.

I LOVE the high tech "Futuristicy" art style, though I'm not sure what I think about the combination of that mixed up with destroyed stone and concrete walls thanks to the Worm. I guess the idea is that the Worm is so destructive, that it's destroying the actual physical structure of the machine (though, the system is nothing like any computer I've any seen, it's obviously an interpretation)

I found the game mostly enjoyable and I enjoy the technology puns and references - computer geeks may get a laugh out of the dialogue's sense of humor. I did get more annoyed near the latter quarter of the game where I died alot due to a couple bosses and a couple hordes. It's a shame that this game wasn't advertised well, because hardly anybody knows about it and there's never anybody available for Co-op campaign or competitive multiplayer (except for certain Days when the developer hosts game sessions).

If you're somebody that liked Descent or Forsaken, or a computer geek that likes sci-fi FPS games, this game is definitely worth checking out - it provided me with at least 12+ hrs of gameplay (admittedly, more deaths than I'd like). I must warn you that the game may require a strong gaming system, as the frame rate can drop significantly - it has 12-15fps on my Intel HD laptop and drops like crazy when I accidentaly leave Folding@Home on (though, it's CPU intensive anyways, but many players mentioned performance problems - look at the community hub) Due to the lack of community, it's probably best to wait for a sale or bundle.

A very fresh and new concept for an FPS. However, do keep in mind it is horribly optimized and only runs on the best gpus from 2011 and onward.


If you got past the requirements to play what you are left with is a fast paced, puzzle-solving, riff raff of a good time.

This is an underrated little game... A cross between Descent and Tron, with graphics reminescent of Portal. Not without its flaws, but enjoyable nevertheless, which is what matters in the end. Note that these comments apply to the single player campaign only, as I did not try the multiplayer.

Do not buy for the occulus rift. It's very unoptimized even at low graphics and the lag will make you sick.
Otherwise, for normal game play, it's decently fun.

Even though Retrovirus is a classic shooter at heart it brings enough new concepts to feel original. Retrovirus plays like a cross between Descent and Tron 2.0, and is styled like a distopian perversion of the classic Disney game. It really stands on it's own in a segment of FPS gaming that has been overshadowed by big money, high production hits like Far Cry 3, Crysis, and Call of Duty. I've been waiting for an FPS like this for a long time.

This fun little game looks like a mix of Halo, Tron, Portal 2 and Wall-E.
In Retrovirus you get to fly inside the Grid killing flood and saving what looks like P-body or Atlas's head(torso?), your A.I. buddy is some what a mix of Cortana, Eve and GlaDOS, while you are the Agent, the top of the line antivirus and mallware-destruco in the world.
Enjoy the game!

While it doesn't quite have the same punch and omph as Descent, it's as close as you'll get.

I really like the upgrade and downgrading. If you upgrade a weapon and change you mind, you can remove the upgrade and place it into something else. This is a feature more games need to have. The art style is simple but very nice and colorful and it's fun playing around with all the weapons you get and seeing how the scan affects them.

I bought this game on a whim after having the opportunity to watch a friend play a bit of it.

I am really enjoying it. :)

I never played Descent so this style of game is completely new to me. I like the visuals of Retrovirus and the music (would buy the soundtrack). The story is nicely presented in a way that isn't intrusive but not overly vague either. There is enough concrete information given to me to follow along, while enough is left unsaid to keep me curious and exploring for more.

I have been playing on "Admin" (medium) difficulty. The gameplay has been challenging in certain areas but not to the point of making me want to break my computer. I've died frequently but instead of making me frustrated, it's caused me to reconsider my approach to the room and strategy. In other areas I have the freedom to take my time and really absorb the visuals. Certain levels "deeper in the machine" were pretty impressive and I like how the interior of the computer has been portrayed. Some optional areas are so well hidden that I couldn't find them. There is replay value in exploring to find all those hidden gems.

I use a gaming laptop and have not really noticed much in the way of performance issues that some people have commented about on the Steam forum. In some areas there is an FPS hit, possibly due to the size of the map, but it doesn't compromise the gameplay. There are some graphic glitches that the devs could spend some time polishing, and a few bugs (like Oracle speaking but the UI showing Courier's icon). I've broken out of a level once and had to reload, and there are a number of typos and grammar errors in the emails and displayed dialogue that should be fixed.

I've played just over 12 hours and thought I was basically finished. Based on my progress for one of the achievements it looks like I have a ways to go yet! I haven't tried the co-op or multiplayer options yet either.

For the price? Definitely worth adding to your collection simply for some fun.

A brilliant little game (although quite demanding on your PC) if you have the specs to run this game it's certainly worth getting

It's simple, virus-blasting fun
it has a suprisingly in-depth Storyline (if you take time to collect all the E-Mails)
Combat is straightforward and easy to understand, same with upgrading and new weaponary
there aren't any forced tutorials, you're free to charge in guns blazing if you wish or to take it slow and be tactical
The game itself is quite amazing to look at, texture quality is good and the lighting enhances it if you can run it on High
Once you're past the vertigo and motion sickness from the 6-degrees of freedom, it's really enjoyable to control

Certain objectives aren't very well explained
there are a coule of spelling mistakes and pronunciation errors that I've noticed so far (I won't mention them)
this is the biggie and, I can't stress this enough, This Game is TERRIBLY optimised , you need a Beast of a computer to actually get through the later levels when more and more enemies are sent at you, if you have a low or mid-range PC, Do Not Get This Game
when you first start going through pipes and turning upside-down, you'll get quite dizzy or confused, so give yourself time to adjust to it (apparently it has Occulus Rift support but I doubt that's a good idea)

Overall, a good game but it has it's downsides, the big one being the poor optimisation which made me quite sad when my PC started failing to Cope with the later levels :c

This is a one hell of a game, i would think that someone smoking a joint and having a blast playing this ♥♥♥♥ for real :D. The game is too expensive to be desirable (steam 19 euros c'mon guys), i got this from an indiebundle for 3 bucks i got six games and this one was one from it and for that price this was a bargain. I would say that the games true worth would be 6-10 $ definetely not more than 10 dollars, the idea is great the colours are fantastic, the music is really fits the game, the 6DOF is amazing now if you could play this game with Oculus you would propably go insane its full of eye candy even tho the graphics are not AAA its still a chocolate that you will eat as whole.

If i would have to chew things to five things that make this game great, these would be:
Atmosphere (just sit back, watch the colours, feel the atmosphere, get lost in the world of computer..)
Idea (great idea, you are the anti-virus, you are the nightmare of all viruses)
Music (It really adds a lot on the atmosphere, its relaxing and almost sleepy)
Colours (Wow, i could play this game on my 84" projector screen and really lost myself its freaking awesome, i think i see some colors i've never ever even seen in my life its freaking sixth dimension)

This game was actually quite good, I was surprised. It's very fun to zip around in free space shooting virus' with your pew pew cannons. There isn't much to the story, and it's hard to fill in gaps in the story line when the developer seem to cram some story into you via "collectable" emails that are easily missable. The main story line though is quite flat, but the gameplay makes up for it. If you're looking for a shooter that will take you a week of casual playing to complete, then this is quite a good pick up.

Retrovirus's gameplay has a quiet confidence about it. Taking inspiration from games like Descent and Portal and the classic CG show Reboot, Retrovirus puts you in the shoes of a no nonsense antivirus program living inside a computer. What makes it stand out is how injects its own sense of self into the gameplay to rise above these inspirations.

Take the gunplay for example. While the game features six degress of movement ala the original Descent, meaning you can fly around in any direction, the game has health and ammo regeneration similar to what you find in today's cover based first person shooters. You can store a limited quantity of ammo packs and health pods, but most of the time you'll be doing your best to manage your health and ammo as the viruses try to kill you. There's also a skill tree that lets you customize your agent's powerset and weapons loadout, and you can opt to switch your talents around as well for when you run into situations that require some abilities over others. That said, oftentimes in combat I felt like I was always exactly one bullet too short to wiping out a virus, which can get frustrating when you're fighting a swarm. Fighting feels much slower in the beginning until you can start acquiring upgrades and more weapons, but the ammo problem leaves a bad first impression. It does eventually bring the awesome.

Level design is another area where the game shines. While mostly linear, they create good arenas in which for you to fight. Cadenza Interactive has helped make navigation a snap most of the time; the paths through the levels are marked with red and green portals. Green portals mark the way to go forward; red portals mean you're going backwards in the level. In some of the twistier levels where all the rooms start to blend together, this makes finding your way a lot easier. There's also an auto-levelling feature where your ship orients itself to the 'ground' depending on the room you're in, also helping to keep you aware of your surroundings. Finally, there is a 'help' function that guides you to your next objective path, but it's not always helpful for finding the last enemy in a room you have to clear. It also won't help you with any optional objects that the game can throw at you, but half the fun in these instances is hunting down the missing monsters or collectibles themselves.

The viruses themselves look like real monsters and things you might find in Aliens or the Matrix. However, I found the bosses disappointing in the design; they just look like bigger and beefier versions of the little creatures you've fought before. Some variety here would have been nice. In addition to the viruses, there are nodes of corruption that have sprung up all around them that give off a distinct neon purple glow. Clearing these isn't just for show; hovering around them damages your ship. Taking them out gives a satisfying crunch as you sanitize an area not unlike shooting Aliens in the original Aliens Vs. Predator PC game. Unwillingly fighting alongside the viruses are program constructs, most of which look like variants of the AIs from Portal. They give off sad whines when attacked and can be even more dangerous than the viruses themselves when in groups. They add another wrinkle to the shooter formula as you have to manage the zombified AIs while taking down the viruses. It would be nice if they helped you but it's only in the late stages of the game that you encounter other programs that will join the fight. Most of the time they mingle and get in the way, which can be annoying.

The story is what it is: an excuse to get you into fighting a lot of nasty bad guys. What starts as a typical day for you and your handler, Oracle, turns into a nightmare when a worm invades. There are twists here and there, but they are expected for the most part and you won't be seeing anything new here. That said, it's well done and entertaining. The AI programs you meet all have their own personalities and help push the computer story along well, from a bubbly web client to the gravel and static voice of the AV Vault's Warden. The plot is a chase throughout the computer system, and you get to see the inner workings of a city inside your computer. The file systems of the email client give way to the rail systems of the web browser, and the environments do a great job of being varied so you never feel like you're retreading ground... until you hit some levels late in the game that recycle content. Level recycling dampens the impression of the game because it wasn't hurting for content, but the level retreads make the experience feel a little fat. At least the game has a sense of pace to break up the super heavy infected levels with quiet strolls where you get to rearm and plan your next move. One set of levels introduces stealth mechanics that are serviceable enough for what they are. Inside the computer things are never dull.

You can uncover the real world story behind the virus by finding emails hidden throughout the levels. While not as compelling as the game itself, they do add an extra level to the narrative even if it's not as great as the invasion story playing out inside the computer. The humor found in the spam emails you find is too over the top to be funny, but they serve as nice breaks when you don't want to read about hackers getting in over their heads.

Retrovirus clearly has its faults. The game's narrative over-extends its welcome, and some mechanics, such as using your system scan setting to activate alternative uses for your guns, feel tacked on rather than integral to the experience. There is also multiplayer and co-op, which I cannot comment on because I haven't played it. That said, the game makes for a complete packaged experience and the stats screen and Steam achievements will make this game good for die hard completionists. The world of your PC is well realized and full of neon glow wonder. Retrovirus is a breath of fresh air to a long dormant genre while striking out on its own.

Now if you'll excuse me, I'm going to go track down my copies of Reboot to watch again...
