Simple and fun, took me a while to get used to the old schools style strafing again. Areas are cool for voxel, guns feel different from eachother(wish there were more on offer at game start). baddies act differently requiring you to learn each pattern. Very hard. ive gotten to the second stage with the Tank class(High hp) but because of the randomly dropped loot, and my want to clear every room gets me killed before I can go further. I poke at the game every so often, but the difficulty is off-putting, along with the lack of things to do if you cant beat the first mode. if you want a fast minecraft looking shooter that requires you to jump-turn-attack and toss-bombs at the same time PA's good. If you have ever played Dark Souls and gave up at the first boss, skip it.

Not perfect, but fun.
This weirdly-themed rougelike shooter (think Nuclear Throne or Enter The Gungeon, but in first person and you're fighting supernatual mariene life and other demonic entities) is pretty solid overall. The combat is fun, the artstyle is great (it's like 3D pixel art, which is super cool) and the music sets the tone for some deep sea Doom-style shooting perfectly. It isn't without it's flaws though.
My biggest gripe is the starting weapons. There are four to choose from, and each one has it's own super weapon and stats, which includes health. While these could provide some much-need variety, only one of the foor seems useful and is fun to play with. The rest range from difficult to unusable.
The first is a shotgun, which is the good one. It's simple, effective, and works on everything. It's super weapon is a cannon, which deals massive damage but uses ammo and is a bit hard to hit with. Overall, solid weapon.
The second is a... Hook? It's a melee weapon, which I find to be USELESS in this game. It's super weapon is a gun, and like the cannon, it uses ammo, but unlike the cannon is seemsto do absolutely nothing at all. I've tried to expeirement around with it to see what it does, but I never live long enough to try it out because this weapon has a health stat of 3, the worst of all the weapons. Why does the melee weapon, which asks you to be up close to your enemies, have almost no health? It's baffling. Either I don't know how to use melee weapons/this super weapon properly, or this weapon is literally useless.
Third, there's a grenade launcher. This one's okay, except regardless of what weapon you start with, you have a generous number of grenades anyway. So having your weapon shoot bombs seems like a waste. Also, the super weapon is a katana, which seems to be just as useless as the other melee weapons.
Fourth, a crossbow. This one's also okay. It deals decent damage, but it needs to be charged and is hard to hit with, so it seems unreliable. Not entirely useless though. However, this one for some reason has no super weapon, and almost as poor of health as the hook, so it ends up being very difficult to use.
There's a couple other small annoyances with the game. Some of the hit boxes seem unforgiving, and the "randomly generated" floors consist of the same rooms shuffled around, includng the same enemy placement, so the charm of randomly generated levels wears off kinda quickly. However, if you play this game with the one useable weapon, it's still very fun to play. I'd recommend picking it up during a sale and killing a few minutes trying it out, if this game seems interesting to you.

It isn't the most polished game on the planet but at it's core it's simple and executed well enough to be enjoyable. It's a roguelike voxel FPS that's fun just to play a quick game. The only major complaint was a leaping enemy after round four that's near impossible to hit and if you're speed isn't high enough will almost always instakill you.

Alot of reviews hate on this game unreasonably harshly. This is in part from reviews when it was still in developement, or under prior ownership. Admittedly the designers of this game had some management problems and also did not deliver all of the things they promised (such as multiplayer support). What they did do is create a satisfying and addicting shooter.
reasons for this
The game is randomised for a different experience everytime
TONS of items, over 100 I believe
Overall fun and FAST fluid play

I could go into much more detail but it is only by playing the game for at least a few hours that you start to appreciate all the different items/powerups/weapons and how they can interact with eachother. An item that seems terrible 95% of the time may in some circumstance or combined with another become so powerful it is almost game breaking. This coupled with dodging and destroying hoards of 8 bit enemies all the while listening to pumping techno music is extremely satisfying.

Another early access game gone astray, this game had so much potential till 1) the devs are the worst 2) sold out quick 3) released an unfinished game.
The grindy industrial music adds a lot to this epileptic bullet hell fps but everything else in this game is extremely lacking. Stylistically, this game is total garbage. There is no consistency to any of the art you find in the game and the "nautical" of this game is forced in to what seems like a random set of enemies. You're on a nazi ship and you'll find anything from moths to snails if you get the just. They only have two different room backgrounds they apply to rooms with different torch placements. Yes you heard that right two room backgrounds on a FINISHED GAME IN A GAME WHERE YOU ONLY GO INTO ROOMS. And the graphics oh my lord the graphics. These graphics looked like they were made by a 15 year old learning how to use voxel. Holy ♥♥♥♥ are they just flat out terrible.
There is no such thing as balance in this game classes or items. That wouldn't be such an issue if there was such a thing as building your character but its all 100% chance based folks. That boss that gives you double jump which is essential? Well you are just about as likely to find a ♥♥♥♥♥♥ boss who gives you a garbage item. Wanna beat the game as the Tank? Well you might as well play bouncer because you don't need a speed up item or skill. OH BOY I got another dark floor item even though I didn't and will not get a single DARK ROOM.
Progressing in this game is like using a cheese grater as a fleshlight. You have no ♥♥♥♥ing clue if your build will win because you might just die to a totally random room because it was so ♥♥♥♥ing impossible. Its almost like you're not even building to win, you are just building to hopefully surive to floor 7 MAYBE. The first playthrough where you think you're going to win is tarnished when you walk into a room and take 10 damage. This isn't even due to lack of skill, the devs flat out made layouts where if you don't see every enemy in the room and the room itself and react before 1 second 95% of the locations you try to run to will lead to 2-3 damage. Do you feel like you are making it anywhere with your build? No. Never. You seriously will get ♥♥♥♥ing destroyed sometimes and all your left with is why am I still playing this game.
This is game has its fair share of bugs, there are so many I don't even know where to begin.I swear the more rooms you enter the game gets laggier by the end so you might as well just not try to stock up. I've had so many fictitiously good builds and then I get to the last boss and it drops to one frame rate. The only poor soul I got invested into this game has a super computer and after it released as a full game it could barely run at 10 fps for him. Enemies will like the caustic dogs and the flipping monkey men will get caught on room obstacles constantly. Enemies in general will sometimes get stuck in walls and you are literally just trapped in a room and have to restart.
Don't even get me started on their cheesy excuse for an update. They somehow made the game worse and managed to overlook anything any player of this game might want. All I can imagine is the devs for this game sitting at a table thinking "Lets make a floor type that ♥♥♥♥ing blows, a poor attempt at a hardcore mode, and a couple of new rooms that ARE TOTALLY UNBALANCED.". Well thanks devs thats about as good as an idea as sending death threats at Gabe Newell and losing all the poor souls paying too much for your game. The devs even made fun of the players of their OWN GAME on twitter. WHO EVEN ♥♥♥♥ING DOES THAT.
If you are looking to buy an fps roguelite don't buy this one. Please do not buy this. The devs are trash, the game will only ruin your hopes for what it could have been, and it will give you a sezuire. Speaking from a player whos been playing since early access, it is not and it will never be worth your time sadly.

possibly the worst game i have ever played, incredibly ♥♥♥♥♥♥ and floaty gameplay combined with awful music and despite the fact it is out of early access it still feels and looks like an early access game, voxel graphics are not an excuse for lighting that looks like it came straight out of quake 2 and models that look like they were made by a highschooler

Let's neglect the fact that the original dev was a huge ♥♥♥♥ to everyone. Let's neglect the fact he raged like a child for a simple fixable reason and said some messed up things on twitter. Let's neglect the fact he outright cheated the original music composer out of pay, after he put personal pursuits on hold because he was told he'd get paid. Let's neglect the fact that the game got taken down off steam, bought out by a new publisher, and brought back to steam.

Its still an obsolete version of Ziggurat. While there are differences, in just about every regard Ziggurat is a superior game and your money would be better spent on that. This game was enjoyable for the nonexistant price of a humble bundle game, but I can't recommend spending any more than $5 on this.

Early Access Review
Posted: May 6, 2014
Disclaimer: This review is for an Early Access game, which has changed since this review was written. I have no interest in reinvestigating the current situation, so take it with a grain of salt. The developer has released updates since this review was posted.

The game itself is not bad. I've found it decently enjoyable. Not a huge amount of replay value, but I got to the end once. The problem with Paranautical Activity is the developer.

The developers have continuously insulted and mocked people who bought their game. In addition, they have been less than honest. The game was marketed for over a year as having co-op incoming (and as of this review, the store page says the developers are still working on it), yet that feature was suddenly canceled. The developers insist they have been working hard on bugfixes and content updates, yet have not released anything, even missing a promised deadline by over two months (patch is yet to be released as of this review). Furthermore, the devs have been silent on the forums (when not aggresively insulting the people who bought their game) and insist you should visit their website, where they will keep people updated; visiting their webiste reveals no new news in two months, and the last message was just an apology for a delay (that has still not been resolved). And when fans have the nerve to say they aren't being treated fairly? The devs say people are "entitled." Do not buy this game, do not support this kind of rude immaturity from developers, do not support Early Access games that are deceptively marketed.

This game is special.

Initially the game was placed on Steam Greenlight on Aug 31, 2012

Then they had a successful Kickstarter campaign that collected $12,540 USD. (August 4, 2013 - September 3, 2013)

There were issues with the greenlight campaign:
"Code Avarice already set up a placeholder Steam Greenlight page and Steam 'didn't want to send the message that indies can seek out publishers to bypass Steam Greenlight.'"

But Officially, the title got Greenlit by 8/28/2013.

Subsequently, in October 2014 the developer threatened Gabe Newell's life over a Steam listing issue associated with the title.
"harsh lesson Paranautical Activity developer Mike Maulbeck learned today when after a Steam snafu erroneously advertised his game as an Early Access title he crossed a line and tweeted a death threat to Gabe Newell. Following this outrage, the game was pulled from Valve's distribution service."

Needless to say, the developer didnt handle the situation and associated fallout well:

This caused the game to be removed from the Steam store, the offending dev to resign from the studio ("Code Avarice"), the "Paranautical Activity" IP to be sold to another company ("Digerati Distribution & Marketing"), followed by the offending dev rejoining his original studio.

On the Early Access Steam store page, they claimed "We're planning to add multiplayer co-op in the very near future, as well as a ton more content, and of course some bug fixes and polish."*/

They also claimed that:
"Paranautical Activity multiplayer is definitely a thing that is happening...We’ve been really busy trying to get MP working...The multiplayer patch will be going live before the year anniversary of the game (february 14th)[2014]"

Subsquently, the devs disclosed that they would not add a multiplayer mode.
"Sorry to those who purchased this game under the guise of the fact it will be multiplayer. We just couldn’t rebuild the entire game to make this happen, there is only two of us.”

Allegedly, the devs were asking for good reviews of the game and doing some "heavy moderating" ie. censoring of negative critique, on their forums.

The offending dev claimed he was "quitting the video game industry."
However, he is already working on 2 new games:
"Arkshot and Timefight Zone" as of 4/2016.

Wow! I did *not* expect this game to be so addictive and absolutely satisfying. A long-overdue and well-executed fast-paced, circle-strafing, old school twitch shooter feel with a lot of elements very much like Binding of Isaac (a very good thing, and I mention the likeness only to its credit.) Different starting characters/builds with different stats and starting weapons to choose from, randomized/procedurally generated rooms and floors, health/armor/gold/bomb drops off enemies, shops on each floor, tons of unique personal upgrades to buy or earn at the end of each floor, etc. With even more content to come, and co-op multiplayer on the way (dear god yes!), I haven't been this pleased with and addicted to any indie title since FTL.

Most importantly, the core controls and mechanics are an absolute joy. The pace and precision of the controls and the action feel absolutely spot-on. This is something many games destined for mediocrity have overlooked in lieu of trying to do everything else. When it comes down to it, the core mechanics, the precision and pacing of the controls of any shooter are at *least* half of what we either enjoy or can't stand about them. And more often than not, we barely even consciously realize that, if at all. Paranautical Activity absolutely nails it in terms of *exactly* how a shooter like this should feel, and it's a feel that is too rare these days. As a pure gaming experience, this one is a huge breath of fresh air. Bravo!

would have expected more content from this game after 10 or more tries the rooms just feel the same, hasnt been a memorable update to the game if there even is one. only thing that sames to keep you going are the boss fights plz give some other incentives
ways that would improve the experience as follows;
- Make the main menu more presentable just looks quickly hashed right now.
- More weapon variety and costumization with weapons than the 4 you can use now.
- Give the world of Paranautical Activity a personality e,g charm, character instead of a dark dreary boring rooms even binding of isaac has personality not only through it's art style but through menus/enemies/environment etc.
- Don't ever resort to normal text font for the shop items or anything other than your own, if it isnt worth it to you it isnt worth it to people to play.
- continue with the funny name approach with the guns
- update more regularly atleast month to month bases if it cant be done weekly or alternate weeks.(more reason for people to play everytime there is an update)
- maybe even the option to play with friends online/local co-op through the game (easier said than done i know)

at this place in time i hope it gets improved but right now it isnt really worth it to play
the points are coming from a fellow artist and game developer wishing better for this game

How this got onto Steam is beyond me, every sound effect sounds like it's either been lifted from TBOI or a freesound site and there's seemingly 10 items tops and I managed to go into the exact same room layout (and enemies) 4 times in one level.
I'm glad I got it with the Humble Bundle because if I'd actually paid money for it I'd feel a lot more cheated.
It hopefully will become worth playing over time but I don't know why games can't just be worked on and basically finished before being thrown out, the entire thing screams first-game-made-in-Unity and is trying way too hard to be The PainKiller Doom Binding of MineQuake.

I should probably have seen the Early Access reviews before purchasing it, but this is where you get a bit more savvy about positive reviews than negative ones.

And frankly, this game isn't too bad. It's just not... fun and doesn't feel too interesting. Think Doom and Binding Of Isaac, but with a worse Health system, weapons that feel powerless at times, and surprisingly bad frame drops at times.

Paranautical Activity (Deluxe Atonement, for its re-release after the minor controversy), is a rogue-lite FPS game, that seems to take notes from Doom and Binding Of Isaac. Yet, it seems to do it in ways that work against the game. While it does use some of the things (fast paced shooting, randomized rooms and floors, varying stats on each character), it doesn't use it well.

Weapons feel quite good to use, although some of them feel rather weak. The shotgun, from my point of view, felt like the biggest let-down of all the weapons, with the bow being powerful and one or two-hitting enemies, with no problem.

Power-ups feel nice too but with next to no proper explination as to what they do, when you pick them up, leave you to guess what they do, for whatever situation you're about to plummet into, with said power-up.

Enemies are... alright. Mostly tedious to deal with, since some range from simple "fire a bolt, wait for a while, rinse and repeat" to "'bullet hell'-like spam". Surprisingly, the most annoying enemy I faced was the floor sharks. Why? Tank-y characters can't dodge well, and with the floor sharks, I've ended up being juggled by them, shooting them with a shotgun that did abysmal damage, until I either died or completed the room that way.

Levels are pretty much the same square box, with randomised preset props, and enemies are dumped in when you enter. Nothing to write home about, except for what could amount to some problem with moving under staircases. Ended up getting stuck there, which has broken the flow of gameplay, quite a lot. There also seems to be some odd dissonance with the enemies that spawn in some rooms? Sometimes you get enemies who spawn in there, who get stuck in parts of the level geometry and just kinda... sits there.

The characters have different spawn weapons, health and speed, meaning that you have some variety in what you can do and can't do. And by variety, it boils down to how far you can get with the fast characters. I mentioned above that the tank-y characters are slow, and even the extra health they have, just makes them a sitting duck until they die. Along with some of them getting weapons which would be ideal for fast characters, since they promote "attack-retreat" tactics, they work against the character, requiring them risk taking hits, which they most likely will, to pump in shots that don't feel like they do much. Compared to the bow or the sicle, the shotgun feels like the ♥♥♥♥♥♥ pistol you throw out the window, as soon as you see anything remotely non-pistol like.

The bosses are... okay. They look interesting, but their design and looks are pretty much meaningless, since most of them just fire shots are you, non-stop until they spawn enemies or do some third thing that makes them slightly different from each other. And, honestly, they could be interesting if most of them didn't feel like the same boss. They just move around the area and shot, not really doing anything else, than the animation their set. Which sucks, cause the bosses I fought, looked really interesting.

The game itself, is it worth it, even after all that I complained about? For some people, if you've run out of rogue-lite games, akin to Ziggurat, it could be. If there's some more tweaks to the game, such as a revamped health system, characters and weapons being buffed, as well as some changes to make bosses less dependent on luck or power-ups, it can be a very fun game. Also the font is pretty damn ugly to look at, in the menu. And the menu looks really amateurish, which is kinda sad, considering a lot of indie games do a lot to make the menus look presentable.

Was I satisfied with the product? No. I felt like I bought a game that could've benefitted from more time in Early Access, especially now that we have a new dev team who works on the game. Hopefully, some future patches can make them game more fun to play and less annoying to deal with.

Do I recommend it? As you saw above, I don't. If you want to jump into the genre of rogue-like or rogue-lite or whatever the cool kids call it, look for a game like The Binding Of Isaac, Ziggurat, or look up some games within that genre on your own. If you really want it, prepare for a game that you may dislike or find too tedious to keep playing.

The game had lots of promise, and planned features that won't ever see the day. The developers, in the steam store page, say "We're planning to add multiplayer co-op in the very near future.." and now they have scrapped that feature entirely without any sort of compensation to the people who bought the game for this exact reason.

Do not buy this game. Do not support Code Avarice (the developers) in any project they choose to move on to. They've taken our money and they've abandoned their game.

As for the actual review:

Pros: Rogue-like FPS.

Cons: Very shallow. Clunky movement. Everything feels the same after playing for 5-10 minutes. There is just so very little content that it is insulting to call it a Rogue-like.

"Yes with an if, no with a but"? I wish there was a "sort of" review recommendation option. If you watch one single video of the game for more than 10 seconds - congratulations you have seen every single thing it will ever do. What's good about it is actually quite good - the old-school movement and shooting - but it's so incredibly thin on content and doesn't quite nail the execution well enough to recommend it. I feel like someone needs to sit these people down and explain three things to them very clearly -

1. Your game is really not interesting or varied enough to have the rogue-like No Saving Permadeath concept attached to it yet.

2. If you are going to go shallow as a puddle, execute the living ♥♥♥♥ out of it - movement and shooting should be like butter, not kind just 70-80% there and rough as ♥♥♥♥ at times. If you are going to go for random procedural stuff bigtime, you need an awful lot of it, not just the same rooms and enemies over and over again.

3. Please go and play Robotron some more until you understand points 1 and 2.
