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.
Grab combine energy balls from a reactor, power up a console and unlock extra spawns (and in the example an Armory) for your team.
This armor is a single map entity, with the option to configure what type of weapon it dispenses.
In this shot you can see the hint that is displayed when a player attempts to USE an enemy armory.
