I've never really been one to play shooters. But then again, I was born into the N64/PS era, and didnt get into gaming until the GC/PS2/Xbox era, by which time Doom, Quake, and UT had run its course. So i've never really been able to experiance the "twitch shooter", only the tryhard big-budget military horsecrap.

Until now.

This game has what most modern shooters don't: a sense of speed, INCREDIBLY tight controls, and... dare I say it... fun? This is the most fun I've had in a while, probably since i was a starry-eyed kid playing Sonic Adventure 2 Battle. Enough exposition, let's get into it.

This game doesnt seem to have a story, except what you can glean from the enviroment, the enimies, and the title of the game. Here's what I've discovered (speculated) so far... (i've only made it to level 5 at this point) you are onboard a nazi submarine filled with demons and demonic sea life. Why? Who knows... and who cares? Just stop thinking and shoot what moves.

Speaking of shooting, the gameplay. Its just sublime. Sublime, and insanely difficult. This game follows up on its promise to harken to rogue-like games (is that how you say it?), with randomly generated floors (specific rooms are premade, but increase in variety as you progress), a Spelunky-esque shop, and a powerup system that brings to mind The Binding of Isaac. The game features permadeath, dying will restart you at floor one. Do not pass go. Paranautical Activity has several different classes, each with its own primary gun, maximum health pool, firing rate (an attribute determined more by the gun than the character), and movement speed. From the shotgun toting Tank, to the Insanely quick but flimsy David Bowie (armed only with a crossbow), there is a playstyle for all kinds of people here. Regardless of your class, all of the primary weapons in the game have infinite ammo, which i personally enjoy, as this game is stressful enough without having to manage it.

When you're not shooting in PA, you're going to be running and jumping for your life. All enemy attacks are either projectile attacks with travel time or rushing you down in melee. Mostly the projectiles. You are tasked with avoiding damage at all costs, which can become rather hectic in later stages of this game. Your character, regardless of class can jump a good hight, and changes directions midair on a dime.

The Graphics are kind of minimal, but I really dig the lighting system. All ingame models are voxel-based, with the enviroment textures looking similar to old-school Doom games. The Soundtrack is surprisingly good, and fits the game well, albeit being a bit repetitive.

All this, and the game is still in beta, and it can only go upwards from here. The devs are talking about adding in co-op (PRAISE THE LAWD) as well as finetuning the gameplay experiance.

This game does have a few bugs. Which is to be expected, as it is a beta, but bugs and minimalist graphics cannot hold back this pure, unadultered, virgin, twitch shooter experiance. Even in its current incomplete state, this game is an easy 8/10, and with solid netcode (fingers crossed), greater room variety early, and maybe a few more playable classes (one that starts with the M4!?!?) this could be propelled to a 9.5 to a 10, easily.

THAT BEING SAID. This game is not for everyone. It is difficult. Its inherent mouse acceleration can be very tough to get used to. If you dont like shooters but like Rogue-Likes you wont like this game. If you like shooters but hate Rogue-Likes, you probably wont like this game. In my honest opinion, this game is pointed at a very specific pocket of gamers, which quite honestly I see as a good thing. Too many game devs these days (mostly AAA ones) are spending way too much time trying to appease everyone (which is impossible) which simply results in a watered-down product, a shadow of what it could have been. YOU WILL NOT SEE THIS HERE. If you dig a challenge, love old-school movement-based shooters, AND like the randomless of Rogue-Likes... welcome home.

Take Doom, add some roguelike elements, some bosses, items, neon lights, crazy music, and you got Paranautical Activity.

For 10 dollars, it's worth the few hours you will put into it. If you like old shooters where you move fast, and roguelikes, this is for you.

Enemies are all unique, tough the limited content makes it a bit repetitive after 30-ish long playtroughs, given you get fairly far.

Still worth it.

-Fast paced shooting in the style of games like doom and quake... I pretty much ripped that right off of the description of the game, rest assured they were not lying.

-A good number of diverse classes, (six) with different weapons, speeds, health, and all the things you would expect.

-Pretty good soundtrack (although to be honest, with this type of game i prefer to hit up a nice dubstep mix on youtube or pandora to accompany my mass murder)

-Cool mini bosses and level bosses

-Fantastic lighting effects (mostly from the explosions and enemy deaths)

-Some very cool rooms, level design wise, further on in the game

-Lots of different items and powerups

THE BAD (Note- this is an EARLY ACCESS title so many if all of these shortcomings will most likely be addressed in future updates and patches)

-Few enemy types (I think there are actually more bosses than regular enemies, which seems rather odd)

- No sound effects for any enemies... Which makes fighting a flying whale blowing lasers orbs with moths above you shooting laser tracking orbs somewhat less dramatic.

- Minor bugs, I've only experienced one bug ever, but it caused me to have to restart. I came out of the elevator on the second floor into a room with no doorways out.

OTHER FEATURES (aka things that you may like or may not, depends on your preferences)

- Voxel style graphics except for walls, stairs, and the ground. I find that the contrast between voxel and non voxel makes the game look considerably better, but that may just be because i don't really like voxel graphics.

-Roguelike gameplay elements, namely permadeath

- I personally have found a lot of enjoyment out of this title despite my initial hatred of the graphics style. Also, since it is in early access, it will continue to get updated with new features and bug fixes. I feel that the developer has a great game on his hands that should definitely be played.

yay reviews i can finally stand on a soapbox and preach my opinions to nobody

I want to like this game, I really do. I remember playing the earlier versions and thinking, "man this could actually be something with more active weapons and varied level design". I personally cannot stand the music at all (it's incredibly obnoxious) and plenty of people criticize it for using voxels because MINECRAFT, but I looked past those faults because I really liked the gameplay. However, the devs get so close yet end up so very far away from realizing the potential of this game with every update - add more enemies but don't add more attack patterns for already existing enemies, switch from random weapon spawn to classes but remove difficulty via adaptation in the process, add more bosses but don't fix the fact that bosses either spin around in a circle or incessantly +forward into you, finally add being able to hold a second weapon but make it a fixed "superweapon" that you can't switch out from, etc.

The game screams "I WANT TO BE A GOOD DOOM AND ROGUELIKE HYBRID BUT MOM AND DAD WON'T LET ME BECAUSE WE WANT PEOPLE TO BE ABLE TO USE A CONTROLLER (which completely defeats the purpose of the free movement currently exhibited in the game)"

Horrible support, you post a bug report or a suggestion and get banned from the forum without warning, checking the developer's post history shows only arrogance and ignorance, too bad.
