I'm skipping the bugs and falling through map. Let's say you get this game playable. The design is so bad they should pay you to get the game and play it. Monsters spawn right IN you non stop, there are levels where they just spawn flamer guys non stop that run with 100000mps and shoot from half the map away and you can't run away from them because they spawn more behind you while you run away. Not to mention the insanely bad weapon gameplay design. You get weapons in turns, and for the old weapons there isn't any ammo left so you're forced to play with the current weapon, which runs out of ammo instantly and you have to collect non stop while getting monsters spawned IN you. I haven't seen design this bad in 20 years of first person shooters. It isn't even worth the bandwith price if you were to be given the game for free to download. Save yourself the pain.
