Contagion isn't your average Zombie Shooter but instead takes a more realistic and different approach to the popular genre with unique characters, environments, weapons, items, and a built in system that makes every round completely unpredictable with resources, objectives, and paths ever changing.

Contagion - Sept 14th Update :: Significant Improvements, Update on Linux/Mac, and More



Today's update may seem smaller than it really is which has more to do with a great deal of work than the lack there of. Since our July 31st/August 1st release our focus has been on the Free 1st DLC Bundle and the Core Game Mechanics much of which is still being prototyped and tested for upcoming releases.

There hasn't been a single day of inactivity and we may have some additional surprises coming your way. Even with me flying back home to the States to save the Company additional expenses and get me on a timezone to better run things with Alex Wright (COO) I already have a powerful NoteBook to continue my work and everyone knows what they're do. I will also be making my first public appearance via a popular Talk Show on October 10th, Sponsoring and Running a Large Venue with 32 high end machines in the center of ZombieFest (with possible special guest appearance), and I think we might hit up Universal and/or DisneyWorld (never been to Florida) the day before we return.

Our Changelog is missing a considerable amount of AI Code, Optimization to Code, and further steps towards including the features we've mentioned such as an improved and much needed lobby system for those not wanting to go through the trouble of setting up a server which requires the usual Port Forwarding and more or 3rd Party Lan related software, New Animation System for our MoCap Animations, Ranking, Unlockables, Stats, and cosmetic options for players.

I will not see my family for some time as we sort Immigration which means I will be lost in my work. This year is going to be a very exciting year!

Check out today's Update (Including additions that didn't make it in the Build Changelog Text)-

Contagion - Update September 14th Changelog:

  • Added new gates to CE_StoneCreek

More updates coming and without the major delays!

Very soon we will be leaking more about the upcoming Free DLC as you may have caught some of that in the past. All 4 weapons are nearing release status, All 4 new characters are looking great (Manuel, Yumi, Mia, & Curtis), Both Maps again right on track, and Flatline is looking very promising. There are rumors of a release date and originally was planned for 3rd quarter but too many deaths, babies, and overhauls have led to delays. We have no doubt that we'll release before years end only our 1st Free DLC Bundle and we promised 2 but while we have an internal date we do not have a public ETA just yet.

I've mentioned this before but the Engine we're currently on has led to numerous brick walls when trying to do as something as simple as creating working Linux Binaries let alone Linux & Mac Platforms. It wasn't built for it but we have a few tricks up our sleeve to try and sort this out. If for any reason this does not pan out our only option is to update to a later Engine which considering the fact we gutted the original for the most part is not an easy task.

We are currently interviewing some of the best and brightest to either work it out or take up Valve's suggestion to move to a new Engine which will require some delicate coordination so that we can still update the existing Engine while building up on the new. No matter what happens our goal is to keep our promise and release on both Linux & Mac. We owe it to our fans but more importantly to those who made sure we hit that Stretch Goal! I rarely make promises so I never have to break em and I don't plan to break this one.

We highly recommend Linux and Mac users NOT purchase Contagion until this is sorted unless you're comfortable with Wine or Crossover.

Again I am flying back home and this will require a lot of effort to get setup with me passing my work to the team but not being as available as I've been with the community (I will do whatever I can to sort this out ASAP and maybe sooner than I expect). This includes our Weekly "Friday Frenzy" Twitch Stream & Giveaway. Some good news on that front is we've got an eager member of the team working out a SFM intro with a new music track specifically made for it when it will most definitely start back up and may even return with DLC in mind! For now please enjoy the latest Episode 31 (check out any else you missed as well as Contagious Gaming Playlist)!

Expect a pretty epic year! Wish me a safe flight(s) and remember just cause I may not be around for a bit the team is still working day & night and your support has always kept us moving steadily forward!

This is a draft review, I'll rewrite this word-hurricane later, treat it like a blueprint.

The game is late by about 8 years in terms of graphics, animations, gameplay and just about anything else you could name. It costs about $20, but for that you get about 3 coop maps and... 3-4 PvP maps. That's it! The game modes do not differ greately, except the coop ones of which there are two and they get boring rather quickly. Maps do change, but the routes are easily remembered, there are about three variations for each coop map, but if you ask me an occaisonally open door that was closed before does not make much of a difference, the tasks are varied but like I said only change twice or thrice per map.

But this isn't even the biggest problem. The worst flaw of the game is what is meant to be its selling point. The devs have made the multiplayer system so difficult and broken it is impossible to join your friends server (trust me I've spent 4 days trying every single solution on forums). The only way to do so is to download third-party programs like Hamachi and I have no intention to do that since I've had less problems joining in a 1999 System Shock 2. The devs are aware of this problem, but they don't want to fix it. Trust me, as I have spoken to them and they say they are denying any bit of constructive criticism. I think they are hinting at that "rent a server" feature instead. Pay-to-play? No thanks. And if you don't want a server and just want to play with your friends, be aware that numerous people will join as zombies 5 minutes before your escape in a 30 minute map and eat you and your friend alive, and they will pick your server out of about 500 empty ones available, yeah the community is nice too.

(A link to the discussion: http://steamcommunity.com/app/238430/discussions/7/540743212111472871/)

This game is in development hell, essentialy you are buying about 5%-10% of what is promised. For this price, there has to be something like 50% more weapons, a campaign mode, 15-20+ maps, a working multiplayer, less bland characters that only differ slightly in voice and hand textures. But more than that, it should be somewhat playable because the balance is broken hopelessly (I'm talking about coop, since nobody buys these games for PvP), three guys vs. three zombies is an impossibility. In fact, one zombie player against 5 survivors gives the zombie about 70% chance of winning, as I have never seen zombies lose unless it's near the very end of the map. The maps are confusing, the directions are seriously broken, people spend 30 minutes trying to fight off zombies looking for an escape truck just to find it half-way through the map in a random detour.

"Realistic" zombie games were the talk of early 00's and many mods were made for a number of them, some were free and more complete than this. If it came out then as a mod, I'd download it and spend maybe two nights for fun, but to pay for something like that in 2014 - no thanks.

The fact is, the game is hopelessly overpriced and late and devs need a reality check. It has no point and no outstanding feature, you begin to wonder as to what the actual point of makiing it was. It isn't realistic enough to be the Arma of zombie games, it's not arcade enough to be for ♥♥♥♥♥ and gigles like l4d, it doesn't have much content to brand it as something inbetween these two zombie extremes. My verdict - the game 's like a random bored zombie that won't even chase you after you poke it, you can just walk past.

If you do not believe a single word I've said, look at the percentage of people that have got the easiest achievements for this game. It's in the decimals for most of them, because I'd bet this game is "enjoyed" mostly over LAN by devs and their friends, and anyone like myself who likes to buy random stuff and make reviews knowing even before the purchase what the game will probably be like anyway.

A little edit: there is a positive review up on the site, that is more popular. It was not removed, although it is early access, unlike reviews by Mantis and other people which were outright banned. Although I might see the logic that it was perhaps, not entirely about the game and more about the attitude of the development team, they were stating an opinion and so should not be banned. I don't see the devs removing the positive Early-Access reviews, so this is hardly fair.

(Final Release) I do not value this game anywhere near $20 right now. The release of the Contagion SDK might change the amount of content available for this game, but right now it is seriously lacking. The description of the game on this store page just sugar coats and exaggerates everything.

Initially the game itself is fun. It gets boring quickly with there only being a few maps total and even fewer co op maps. The game goes on sale for $5 sometimes, I recommend this game at that price (especially if you go into it with friends). Investigate and watch some gameplay before you take this negative review to heart, you could really like the game.

This game was fun (if sparse) in Beta form. I loved the gameplay and feel, but the full release actually seriously downgraded the graphics and character models, and movement feels much worse now. I innitially was very excited for the "Escape" mode and played the 1 map they had to death and back. On full release there is.... 1 more map. Actually, it is the same map as a Beta one, just repurposed for "Escape" mode.

The difficulty setting means nothing as far as I can tell. On normal I had a lot of ammo I thought, but died miserably about 20 minutes later after finding little more than a box of pistol ammo and an old shotgun with a couple rounds in it. As for the horde of 100+ zombies outside that will follow you no matter how far you run or hide from them, they tore me to shreds moments later. This brings me to another fault of the full version. NO ammo (and I have yet to have a single melee weapon spawn) or FAR TO MANY zombies. There is no balance since the undead can auto track and lock on to you.

As for my skill, every shot (minus one or two when a zombie stealth sneaks behind me) is a headshot. MOST of the time, this is a kill, and other times it takes 4-5 shots to the head to bring one down. Still, if the game lets me have a good run and the hit boxes are in my favor I can get 99% single shot kills. Still, I run out of ammo and end up being swamped by a horde despite checking every nook and cranny for guns and ammo.

Character models now look TERRIBLE! Seriosly, there is something badly wrong with their faces and the textures/models seem to be between Half Life 1 and 2 for quality, while the zombies all look good still. Gore is alright, but the zombies make NO NOISE at all when they walk and make the exact same noise as a door breaking when they die/fall.

Before the "full release", I would have rated it a 8/10 with high hopes as it only needed more maps beyond the police station. Now? I would say 2 or 3/10, and that is being generous.

Lots and lots of potential but there are some absolutely game breaking flaws.

Headshots just don't register sometimes, be it a random pocket of air that stops the bullet completely or a headshot putting a bullet in the shoulder.

There's enough realism to have to unload your gun before you switch to a new one but not enough that your character calls out to the survivors in extraction? I can't tell you how many times I haven't even had a chance to loot some desperately needed ammo because the two ♥♥♥♥♥♥♥ in the house that are apparently EXPECTING ME don't know how to take a step out of a corner. This could be fixed by my character calling to them (Which would make much more sense for starting the holdout phases instead of just opening a door) so they make their way to me and I'm not stuck fumbling around in the dark for them WHILE THEY'RE BEING MURDERED. As far as I can tell the nail gun is 100% useless. I might be missing the nail/ammo packs laying around or something but even then... You don't have time to use it. There's no preperation, you open the door and there's a hundred zombies within 50 feet of the holdout area.

Melee does absolutely nothing. No, it does something, it gets YOU hit while the zombie doesn't even react to being pistol whipped.

There are some very atmospheric moments that gave me a real rush while playing but the previously listed problems kill the experience, I would recommend this game a thousand times over if these blaring flaws were taken care of.

(Maybe it would be a good idea to add another mode to appeal to both kinds of zombie fans? Slow walkers that require headshots are fun but so are the fast/fragile sprinters.)

Would unfortunately not recommend yet. I am very surprised that this is supposedly a "finished product". Plays more like alpha or beta at the moment. Wouldnt have been disappointed if this was early access, but for a full release- come on guys. Good concept and will hopefully get there, but as of now consider it an early access game with many limitations.

Please note that this Early Access review is not a substitute for a comprehensive bug report.

Contagion is the zombie game purists have been waiting for since they first cracked open "The Zombie Survival Guide".

For me, that's about ten years. For ten years I've waded through a horde of zombie games. Nothing emulated the raw feeling of isolation and cold that a gunshot in the distance or a scream or absolute silence can bring. We're all familiar with Brooks' original canon for zombies. Only headshots kill them. Eat flesh until they can't. Only sensory organs that have not been decayed or destroyed work. A moan causes others to moan, and they are attracted to the sound like a foghorn in the night. I never felt like I would truly find the zombie game that emulated this canon so perfectly. First there was Dead Rising - a close contender - followed by Dead Space [which opened a whole new can of worms] and Dead Island, which underperformed in basically every aspect. Left 4 Dead left a hollow feeling, mowing down thousands of zombies in a few hours seemed not worthwhile. Even DayZ left a bitter taste with its focus on player interaction and intense PVP, zombies were a secondary addition to the game and in their state of bugginess and all-out failure to function were hardly a threat to be feared for all but the newest players.

Finally, though, finally. From the ashes of Zombie Panic! Source comes a developer prepared to emulate and yet transform the genre. Erasing waypoints with Google Maps on a cell phone and slaughtering the idea of overpowered zombies by balancing their frailty with disguise and scarce ammo, this game is reaching for the stars.


Contagion performs in ways I never thought I would see, genuinely. It strikes feelings of sudden and intense panic, a moan can send my heart pounding in my ears, praying it would be silent so I could hear which direction the zombie was coming from. A gunshot can bring hell's fury itself down on your head, while boarding up windows and doors can buy you time to escape. Zombies' interaction with the world largely seems to be directed by line of sight and various audio cues, which gives them a shambling and confused appearance. A slight trigger can send Zack coming at you, but a bullet in the wrong place can mean a bite, and a risk of infection. Incentivized by kill count and bragging rights, a human infected is unlikely to share this information with his teammates for fear of being shot on the spot. A group of humans prepared to fight off a horde of 50+ shambling corpses can easily be dissuaded by a misaligned headshot tearing off the jaw of a zombie and inspiring panic in the squad. A misplaced shotgun round can result in legless zombies crawling under the horde and into your lines. Brutality, free-for-all, and all out panic. All of it rings true of the first days of the Zombie apocalypse, and all of it brings a warm feeling of nostalgia to my heart, and hopeful eyes for the bright future where the Zombie genre isn't filled with crafting games, 8-bit indie ♥♥♥♥, and quick time events.

Even the zombie player gameplay has merits. A helpfully designed "camouflage" button allows an inept player to disguise himself as he views his zombie in the third person and have control assumed by the AI. Moaning loudly can draw a horde, and in turn the moans of those zombies draw more, which can be lead to the human's hideouts and used to swarm them. A biting function has a high chance to infect humans, and watching your former counterparts murder each other for fear of infection in their hideout is rewarding in its own regard.

I've never been so happy to realize a game was early access. After about 30-40 hours, I can easily see myself growing tired with this title and passing it into novelty, but it was well worth the 3$ spent. Call me nostalgia-blind, but there's so much potential content to see from these developers, and I'm very excited to be along for the ride.

18/10, buy this and buy it for all your friends. This game will make history, and if it doesn't, I'll eat my shoe on livestream.
