Thanks to the "Unlimited ammo", I quickly killed the puzzle with Anti-tank weapon . Thanks to "One Shot, One Kill" I quickly killed Bobby and Eddie. In the "slaughter mode" Frank moves faster, so most of the game is runned in this mode, but the knives sometimes fall into the wrong target, at 50:18 I got into civilian.

I also found two jumps: at 29:12 and at 42:44
