MOTHERGUNSHIP

Have you played Tower Of Guns? If yes, this is basically Tower Of Guns but WAY better. If you haven't Tower Of Guns was OK but seriously just buy and play this instead.
Mothergunship is a ridiculously over-the-top bullet hell FPS with the right balance of thoughtful strategy and reckless abandon. Lots of fast-movey-shooty-dodgy gameplay against swift vicious hordes, turrets, minibosses, and more. It's fun and challenging, and has enough variety that combat doesn't feel the same in every room, and you will have to change tactics often.
Movement is, literally and figuratively, a blast. If the standard triple-jump isn't doing it for you, it's possible to upgrade and get more jumps, and even collect powerups that increase the number of jumps you can do. And if all that fails, it's possible to equip a gun with knockback that can launch you right up to the ceiling. My only personal quibble would be that it would benefit from having a dash button, but considering this game was made before "FPS dashing" became a thing, it can be forgiven (plus it's possible to just jack up your character's base speed to a frankly ridiculous level).
The "build your own guns" mechanic is every bit as fun and crazy as you can imagine, with enough variety and supporting mechanics to require some thought as you're putting your guns together. It's possible, for example, to create a gun so powerful that every shot drains your energy, or the knockback will blast you out of a weapon's usable range.
What's really neat is how most missions are a gamble. You have a stash of gun parts you keep from your successful missions and from buying them at an in-game shop, and you can start each mission with a select number of parts. Of course you want to take your best parts with you if possible, but at the same time you might not want to take your best stuff into a new ship type or with a level much higher than you're used to, because if you die on the mission, you also lose whatever gun parts you were carrying. It's another layer of risk/reward that I really appreciate.
If you're looking for "cons", I'd probably mention that the story is kind of meh at best. It's meant to be comedic, but the bulk of attempts at humor are either "support characters bicker at each other", "the guy in charge is a store-brand Zap Brannagan", or "here's a pop culture reference we found in a clearance sale".
It also does this thing that annoys me, but your mileage may vary - XP is collected via enemy drops that despawn after a short period of time. I don't hate this system, but I do feel like "experience points" are meant to be an abstract representing a character developing their skills by learning from their experiences. So it seems weird to be like "I have learned nothing from this experience because I didn't pick up some loose change before it disappeared".
So all in all, I can highly recommend this game at the asking price.

After a long day of work, errands, and chores, THIS is the game i want to play. Mindless shooting with satisfying weapon construction. 39 hrs in and i havent finished the story, I just grind. Would recommend for fans of FPS, Roguelikes, Engineering, and Robot-on-robot violence.

Begin with spare parts. Make small gun. Start level. Kill stuff. Get other parts. Make bigger gun. Rinse & Repeat.
Also has cool music.
Recommend - Yes

There are fun aspects and frustrating aspects to this game. Overall, the fun outweighs the frustration, but not by much.
GOOD: While the idea of customizable guns is cool, this freedom usually cannot used that much in a normal run, as coins and time are limited. That is, you either die or finish the level before being able to afford a humongous gun with more than 3 barrels (an exception is endless mode).
That said, having two guns with three barrels each, shooting shot gun, lasers, rail guns, machine guns all at once, is a pretty awesome feeling!
The characters, writing, and voice acting in the campaign is good and funny.
NOT GOOD: There is not much of a story and the campaign is extremely short. The final boss is a bit of a disappointment.
The game lacks some variety, and after 10h or so it is hard to stay motivated.
Level design is sometimes frustrating. For example, there are small obstacles for no reason where you get stuck and die. And once you touch lava your character jumps up and slides on which makes it harder to get out.

This game has the distinct feeling of being unpolished while simultaneously being enough fun to make you forget about it. Occasionally you'll say, "Oh, it would be better if..." and you'll realize the missed opportunities that would have made the game perfect. Some of these ideas are implemented much later and you'll wish you had had them the entire time. If they make a sequel I can only imagine the perfection they would achieve by tweaking their various systems and making the game even more fun. Absolutely play this. It leaves you wanting more in a bad way, but you'll enjoy it all the same.

This game is an underrated gem. Its not without flaws, but its a damn fun experience in its own right. In essence, its DOOM 2016 but roguelike. Its very fast paced combat where you rarely ever stop moving, dodge a thousand bullets and blow everything up. You collect gun parts within levels, build guns with them and use those guns to shoot robots. At the end of the level, you add your gun parts to your own stash that you can choose to bring in with you to other levels, but if you die in a level, youll lose anything brought in with you. That results in a lot of really nice mechanics, like not risking your one good weapon on a potential death level, but making that level even harder as a result. Or, if you lost all your good stuff, theres infinite random levels where you can "borrow" equipment, and keep it upon victory.
Theres no limit to what you can actually build with the gun creator, so putting 30 machine guns on screen is possible but will run out of "energy" (recharging ammo over time) immediately. And most levels (at least up to where I am in the game) arent long enough to allow for the monstrous creations youre thinking of, so the game isnt too unbalanced. Weapon variety is great, with some being terrible and some great, but even terrible weapons will get some use if RNG isnt on your side and you havent got much else.
The soundtrack is solid and fits the game well, whereas the artstyle is a little bit too generic. Surprisingly, its got full voice acting for every character, which was nice, and there are quite a lot of comedic dialogue moments. Although some rooms are all same-y, others really stand out, being flooded with lava or neon lights or moving parts, and are super memorable. Really, the core gameplay is the most important part of this game.
About the RNG: It can be great, it can also be terrible. I never had outright unlucky runs that were just cursed from start to end, but did have issues getting coins in some levels, and then issues finding shops in others. Good runs and bad runs are part of any roguelike, so I dont mind this, but its certainly a downside if you cant tolerate the game giving you little chance to succeed.
I think any game that lets you fly around by pointing your triple railgun behind you and launching yourself away and upward repeatedly is a very fun game indeed. Mothergunship is an excellent gameplay loop that is done well, and despite my short playtime, I think the replayability here is very high.

Interesting concept taken to the absolute extreme. Incredibly fun gunplay and movement. Quite challenging but never overly sadistic or unfair.
