kinda like mine but you can go outside on mine and run around the map on maps 1 and 2 and on map 4 you can just jump out pack a punch wich is open at start lol, mine also has unlimited health for all players and low gravity so the zombies float off etc lol pluss knife range of 999 etc, good fun, heres some codes that work:
"player_sustainAmmo", "1" );
"player_sprintSpeedScale", "3.0" );
"player_sprintUnlimited", "1"
"jump_height", "999" );
"g_knockback", "999999",
"player_meleeRange", "999"
"phys_gravity", "0",
self playerzombie_infinite_health();
