"Cannot cheat from this server" fix:-  This trick will exploit a fatal error when applying the +set developer 1 +set sv_cheats 1 command line parameter, if you get the "You cannot cheat on the server" message. After starting the game with that command line parameter select a new game (or "Resume" a current game and the cheat should work). Set the level and start it. Then, save the game and exit out back to Windows. Restart the game and select "Resume". Do not manually select a game to load. All you need to do is "Resume" your current game.

Rapid fire:-  Use the following trick to shoot multiple shots at once from a semi-auto gun (for example, Gerehr 43 or MP40). When you are sprinting with one of these or other guns, rapidly click fire (default is the Left Mouse Button). When you stop sprinting, continue to click. When you are done sprinting, the gun should shoot three round bursts very fast. If it is a machine gun like the Thompson, it will fire extremely fast.
