Its great, played thru the whole game, a bunch of things could be better that are explained in other reviews. not that long ago there was alot less on steam in the pixel art platformer department and this was a stand out for its time of release

In general the game's great - nice art, silly and crazy guncrafting, great co-op. I've put in plenty of hours and enjoyed them, which is why I'm recommending the title. However...there are some caveats:

1) The platforming and movement can feel unresponsive or sluggish, especially since equipment weight factors into jump distance and movement speed. Why the developers did this, I have no idea. It detracts heavily from the action and punishes you for using fun, large magazine weapons like machine guns. Balance might be a consideration, but larger magazines already lower damage-per-shot, so what purpose does further punishing you by making your movement sluggish (in a timed platformer, no less!) serve? Nothing, in my opinion - it's a decision at odds with the gameplay style. Yes, I'm aware there are ways to overcome this - you can put away your weapon (in an action platformer? nonsensical), you can craft bionic mods (which often come with their own penalties), you can use radioed-in crates to extend your jump... but should the player have to go through all this rigmarole in an action platformer?

2) Some of the maps are tediously designed, with one false move ending your attempt to pass the mission and requiring you to restart the map completely - that's on top of the ever-present timer. They also require very specific setups in order to make it to the end, which you'll likely not realize until you attempt and fail it once. Rush'n'retrieve at Captain rank comes immediately to mind.

3) The timer - every mission is timed. Some are more generously timed, generally when you have to find materials or rescue hostages. Others have such small time windows that they require a flawless run to the objective or fail.

4) Material grinding. It's a tedious way to pad gameplay hours, especially with the RNG loot drops. I put up with it because I played a lot of my time co-op, so it was mostly all done with friends. However, if this bothers you, be warned it's a major part of the game. I'd recommend cheating your way around it, but part of the enjoyment is unlocking new parts because you earned the materials to do so. Be warned.
