It is seen mostly in the lower levels of the Citadel and acts as a "system activation node", allowing the player to start equipment such as powered bridges or the Citadel Core's containment devices. In Episode One, another type of generator can be found, resembling a wall socket.

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.Īfter Gordon safely crosses the bridge, Alyx follows.Įnergy Ball-powered socket generator 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. Generators powering critical systems typically have about three orbs inside them, but ones that power smaller devices will have just a single one. To restart it, a new Energy Ball must be replaced (it can be achieved with the Gravity Gun or the Pulse Rifle). 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. 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. Types Standard Energy Ball-powered generator 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. The Energy Balls launched from the Pulse Rifle 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. There are many more generators in the Citadel than anywhere else, supplying power to systems in the immediate area.Īnyone 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 a Pulse Rifle. Run by Energy Balls and often 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. 2.3 Energy Ball-powered socket generator.2.2 Limitless Energy Ball-powered generator.2.1 Standard Energy Ball-powered generator.
