Cheat Codes!
Just like Doom 64 and Turok, Hexen contains some really cool cheat codes. The first thing you
must do is start a game. You can pick any play mode (normal, co-op or deathmatch) and can
have any number of players. You can also resume a saved game. Once the game is started or
loaded, press start to pause the game. Now press the following button combination: Top C,
Bottom C, Left C, Right C. If done correctly, you'll see Cheat appear at the bottom of the
menu. Go into the Cheat Menu.

The following codes must be done rather quickly inside the Cheat Menu. If you pause for even
a second, the codes will not work. The codes listed underneath the "Collect Sub-Menu" can be
inputed anywhere, but you have to go to the Collect Sub-Menu to use them. If you input the code
correctly, you'll hear a "swooshing" sound. If the code is invalid, you'll hear a "Hmmm..." sound.
