Awesome game, took me some time, but still i beat the last few and I kno wats going on... after collecting all the secret you would c those old movie players and rooms, each room has a movie player and you would c something about the game maker
I found a trick that hlped me to beat it, after you got the sniper, just keep using it, everytime it reloads, click esc, and you would reload while the zombies pause, really helpful for head shots
