Sorry, but this game sucked. I tried playing it for an hour, and I ended up running around the level without knowing what to do or where to go. I kept getting killed over and over because of the terrible reload mechanics. Apparently, you are forced to reload, but none of your enemies are. And you are supposed to press some key to reload faster during the reload sequence, but the game never informs you which key it is, and I could never find out, I tried mashing randoms keys and it didn't help. Speaking of keys, the keyboard controls are backwards. You are forced to use w,a,s,d keys to move and jump instead of the arrow keys. You can change the movement keys in the game, but when you change them, you are still forced to use the w,a,s,d keys to browse menus and navigate dialog. It's like the developers didn't fathom that some players would ever want to use the arrow keys for anything.
As far as the gameplay, it's confusing, there are no difficulty settings, you die and re-spawn at random locations, you lose when you die a certain number of times, and lastly, you have some count-down timer to reach you objective, and you dont ever know where it is.
If playing the first level was so terrible, I dont want to give any other levels a try. No thanks.
