Teamplay and co-operation are key to this deathmatch mod.
Teams take it in turns to defend a fortified base.
Access to the enemy base requires the successful destruction of a perimeter wall or doorway. A button deep within the base triggers the fall of the base to an attacking player. Bonuses are structured to reward teamplay and make it advantageous to take the base quickly and to hold it for as long as possible. This is not Team Fortress , there are no player classes, no new guns and no power up runes. Base Defence was developed using Zoid's Q2CTF code, this was intentional so that setting up a Base Defence server will be as similar as possible to setting up a CTF server.
