I got this during a sale for like a dollar. Worst dollar I've ever spent. Terrible controls, insanely stupid plot, just... no. Just no.
EDIT: I fired this game up again just to be sure it was as bad as I remember... and it's far worse. The default controls are WASD for movement, arrow keys for camera movement(which is utterly useless) and VBNM of all keys for jump/use/attack/equip. Just the most ludicrous key layout ever. You CAN change it to use ZXCVB and arrow keys, which is slightly better, but the keys aren't rebindable. Oh, and it doesn't detect your monitor's resolution, and doesn't let you change resolution.
Config menu aside, the game is utter trash. Apparently I'm running around, with cutscenes inturrupting me constantly, in a pseudo-2D world where I can't tell how deep into the screen my character is (which makes attacking enemies impossible). Nothing makes sense, the character animation is awful, the weapons are severely underpowered (And apparently ammunition is limited or something with no ammo pickups anywhere, forcing me to use the awful melee combat system), the level design is mazelike and atrocious... Just no. Give me my money back. If the game was free, I'd play it for five minutes before dismissing it as trash. As it is, it's ludicrous to expect money for this abysmal excuse for a game.
