This is the best bad game I'd ever play! This abomination, is well worth your time and the money it costs to buy.
Basically, you're an amnesiac killer power-armored psychic bioenhanced cyborg member of a secret fraternity of warrior-monks which is fighting the legitimate government. Truth be told, I barely understand it, but that's not the reason I like it.
It includes rpg elements and character upgrades, including cybernetic upgrades, leveling up, buying superpowers...
Many ways to play; if you want to play the game as a stealthy hacker ninja, you can. If you want to put on heavy armor, grab the (stupidly overpowered) minigun, and pretend you're the Terminator and walk through a dozen rockets and about a thousand bullets, you can too. If you want to summon hordes of clones and unleash them on your foes, you can do that too. Did I mention you can hack enemies into this game and possess or MIND CONTROL them? Well... you can.
If you get bored of guns, you can use melee weapons. And this isn't just a joke, the melee weapons in this game are death machines. You have swords that cause people to literally explode. And you can parry bullets with them like a jedi!
Also, the game's designers and writers are all French, so there is that amazingly hilarious bad translation. Nothing in this game makes sense, but it's a good kind of insane.
And, of course, it has that superb full coop gameplay, really fun.
