This question belongs in the New Users forum, but I'll answer.
1: Unload the maps into you maps folder.
2: Make a copy and paste a shortcut of haloce.exe to your desktop.
3: Right click, and go into your newly created shortcut's properties.
4: In the
Target textbox area, skip to the end of the target and type
-console at the end. (With a space between console and the other stuff)
5: Run Halo Custom Edition.
6: In any halo screen (doesn't matter where), hit the
Tab button to open up the on -screen game console.
7: Type in
map_name mapnamehere (Just the name, not the .map and stuff like that)
8: Press
Enter and play.
