ZapDM is one way Capture The Flag. Your team's goal is to touch the lightning switch at your enemy's base. Just one touch by one of your players will make your opponents explode in a fountain of blood. The catch is that your team must defend their own lightning switch. ZapDM is a mod for Counter Strike:Source written as a Mattie's Events script plugin. There are currently five custom maps built for this mod. The map source, textures and lightning sound is available for the zapdm_exemplis map. Players respawn when they are killed. There are no buyzones for weapons, but players can select which weapon they want by walking through one of the forcefields at their spawn.
