'''Combine Power Generators''' are Dark Energy-powered generators used by the Combine. Coming in several types, they are mainly found within the Citadel, but can also be found in certain locations in City 17, such as the Overwatch Nexus, the plaza visited in the ''Half-Life 2'' chapter ''Anticitizen One'', or near the White Forest Inn, in the Outlands.


Often run by Energy Balls and protected by Force Fields, generators are used to power devices such as Force Field gates, powered bridges, locks or weaponry such as the Suppression Device. There are many more generators in the Citadel than anywhere else, supplying power to systems in the immediate area. 

Anyone unlucky enough to step into or to be thrown inside a generator field will be disintegrated, just as they would be if they were hit by an Energy Ball shot by an OSIPR. The Energy Balls launched from the OSIPR are similar to that of the generators, but the latter are much more powerful, capable of damaging or destroying vehicles and Synths, such as the Strider confronted in the Citadel in ''Half-Life 2''.

With the modified Gravity Gun in ''Half-Life 2'' and ''Episode One'', the player can throw enemies in generator fields and use Energy Balls against them, leading to often spectacular deaths.


===Standard Energy Ball-powered generator===

This type has a core with Energy Balls floating within, which create a beam of electricity that runs from the top to the bottom of the generator. The Energy Balls are the actual objects that generate the power, as when they are removed (with the Gravity Gun, for instance), the generator will cease to function. To restart it, a new Energy Ball must be replaced (it can be achieved with the Gravity Gun or the OSIPR). Generators powering critical systems typically have about three orbs inside them, but ones that power smaller devices will have just a single one.

This kind of generator is the one featured in the Overwatch Nexus, the plaza visited in the ''Half-Life 2'' chapter ''Anticitizen One'', near the White Forest Inn and the Barn Advisor. Most of the time the player must shut it down through Combine interfaces to proceed, while having to protect Alyx or Barney at the same time, sustaining heavy fire from Combine troops.

===Limitless Energy Ball-powered generator===

This other type is found only in the Citadel and have a constant flow of Energy Balls passing along a glowing white beam. These generators are often found in large elevator shafts and open areas found in the Citadel. It is however unknown if these are actual generators or if they just transport Energy Balls (vents located around the Citadel Core seem to fill the latter purpose).

Horizontal limitless Energy Ball-powered generator also exist. They feature sockets similar to that of the Confiscation Field and Combine Prisoner Pod|pod cleaners.

===Energy Ball-powered socket generator===

In ''Episode One'', another type of generator can be found, resembling a wall socket. It is seen mostly in the lower levels of the Citadel and act as "system activation node", allowing the player to start equipment such as powered bridges or the Citadel Core's containment devices. This type of power generator can be activated by launching an Energy Ball into its center, causing its four arms to retract inwards to hold it in place and begin to siphon energy from it. Two of these need to be operational if powered bridges are to be in function, as a powered bridge consists of a pair of lasers, one per generator. 

Stalkers always try to shut down player activated generators of this type by popping the energy pellet with their face mounted lasers.

This type of Combine generator is similar in function and appearance to the Aperture Science High Energy Pellet socket seen in the Aperture Science Enrichment Center, although the possible connection between the two is unknown, and the arms are only three, folding outwards into a flat accordion instead, placing 3 shields along the edges.

===Liquid-powered generator===

Only seen in the Citadel and not using Energy Balls, this type consists in a large cylinder made of liquid matter, with a solid base and top. This liquid matter is likely the same liquid seen in Combine Barricades. It does not seem to be contained in any particular vessel and yields no visible side effects other than massively reduced velocity, while surrounding any thrown object or being with blue particles. The central beam however causes instant disintegration upon contact.

===Simple generator===
Another type of generator, sometimes used on itself, sometimes located near an Energy Ball-powered generator or a Combine Heavy Door. It is prominently featured in the Overwatch Nexus. Its model is also used in the pod conveyors in the Citadel, where two are seen linked together by a laser, acting as detectors for Combine Prisoner Pod contents, and as alarm light in the Citadel's core control room or the booth near the Depot's teleport platform where Alyx traps Mossman.
