MOTHERGUNSHIP

Currently when I'm writing this review I stepped out of a shop/modification room on the first optional mission.
On my right hand I have a weapon that throws balls of varying speeds and effectiveness.
On my left hand I have a heavyweight laser weapon with two precision lasers and a revolving electric caster with pinpoint accuracy.
The left hand weapon is the sexiest piece of heavyweight armaments I've seen in a videogame, I made it myself and I am so satisfied by it.
The game is gunporn simulator with target rich enviroments, it's already one of my favourite games ever.

From my experience this one is the easiest rogue-like game out there after you know the loop
Put a gun on top of a gun, Put a gun on top of a gun, rinse and repeat
Fighting the final boss feel like 10 second only... like what? i already won?
Crafting the gun and use it in battle is the best part about the game and the game is very enjoyable (even thou it's an easy game)

This game is amazing. Fun times to be had in a game that could very easily be monetized but it's not. AND IT'S A BLAST BECAUSE OF IT.

If you love FPS bullet hell, gun building is appealing, want co-op, and are good with procedurally generated levels, then this is a must buy game on sale.  If you don't have friends with this game and you often get tired of procedurally generated levels, then think twice about buying this game outright. I'm 8 levels in but thought it important to review because this game is so awesome, and even if the end winds up sucking, then I enjoyed the rest of it.
The core gameplay loop consists of selecting/buying weapon components to put together, fighting robot/alien enemies in procedural rooms, more buying & crafting between enemy rooms, complete the level to get a mission reward and keep all loot. If you die then you lose all loot you brought, earned, or bought but keep your XP and unspent coins.Progression early to mid game takes me about an hour per level, alternating between main mission, XP missions, and free/pre-equipped missions.
Here is what you need to know:
+ Heavy rock/metal soundtrack fits the game's vibe well
+ The game's campaign doesnt have much of a story per se, but does have ample often amusing dialog between characters & crew in the game, none of which takes itself seriously.
+ Room or room entry modifiers consist of random room tilesets/themes, challenges (success=coins), or reward/gift.
? Challenges are a good variety, but I did get one once that asked me to kill more enemies than how many existed in the small room.
+ Sometimes there are hidden areas & hidden rewards in rooms.
+ There is an endless mode unlocked mid-game, but no rewards beyond XP or coins.
? Sometimes a room is big enough that it has multiple enemy spawn points triggered only when player enters certain areas.
+ If you beat all the spawn(s) you trigger, you have the option to exit or explore more which may trigger more spawns.
? Sometimes there is a nightmare mode mission available which just seems like hard mode enemies that perhaps also triggers all spawns at once in a room. Other twists are that there's a countdown clock before exit doors open, but you can also either defeat all enemies or find a key (in at least half of the rooms) to exit a room early.
? The proc gen is nothing special. If you love the game you won't care about it, and if you dont like the game then you'll complain about levels being samey after playing several levels.- I've only had two real boss encounters out of 8 levels so far. I was expecting more, but maybe the devs might not want to overuse them.
+ Weapon parts are pretty well balanced among their attributes and have a decent variety among part types.
? There can be a lot of strategy around weapon energy and weapon firing in the mid to late game.  Two general level strategies are to either craft lower energy weapons where you hold down the fire buttons then releasing before energy depletes, or craft higher energy weapons where you tap fire buttons just enough that energy doesn't deplete.  It can be a strategy to let energy deplete completely, but then your weapon is unavailable until energy fully charges again, and that full charge might take longer than normal recharge.
? I think I find myself spending a third to a fourth of the time configuring my weapons compared to actually fighting enemies.  The more time you spend with the game, you might spend a bit less, but you get the chance to craft larger weapons in later levels too.
+Performance on my GTX1060 & i5-3570K was decent. 70-100 FPS at Medium to High settings at 1080p. 1440p would have too many dips under 60 FPS in battle. Turn off in game vsync if you have GSync/Freesync enabled!
-Several or maybe all enemy explosions seem choppy like they were animated at 30fps or less. The particle effects aside from the enemy's shell all look great though.

Really fun FPS rogue-like with some elements of bullet-hell. Weapon building is really clever and intuitive. The post-main campaign content is really tough, so be warned!

A fun game to hop into and play for a few minutes. I would not have paid $25 for it but got it from humble bundle and am satisfied.
