Dark Powers (DP) is a teamplay modification for Half-life 2 Deathmatch (HL2DM). DP adds a layer of strategic area control gameplay on top of the standard HL2DM team play. Spawn points are captured by overloading combine consoles with dark energy pellets AKA combine balls. Spawns can also have attached devices to help their teams, such as weapons and health dispensers.
Spawn Points (the metal floor plates with the harzard stripped borders in the other screenshots) can be captured by either team and also be locked, ready or shielded. This can be a bit confusing, so i've added this menu (like the scoreboard), it lists all the spawns in the map, their team is indicated by color and their status is indicated by the icon on the left.
In this example the map has just loaded, the teams starting spawn points are shielded from capture and the neutral spawn points are all locked (so they can be captured with a single energy ball).
