The Ruiner is an Epsilon Headquarters exclusive aircraft that disables weapons of both enemy infantry and their friendly soldiers nearby.

Official description

Yuri truly seems to have an affinity for the UFO, as the Ruiner is yet another one of them in his arsenal. Just like the War Rig, the Ruiner uses an accurately-named 'Amnesia Ray', which effectively makes the enemy infantry "forget" how to use their weapons. The beam contains a complex combination of some of Yuri's finest chemicals, designed thanks to his careful studies on human genetics, in order to manipulate their senses and state of mind where it affects them the most. Paralyzed by the chemically-induced amnesia, the affected troops will not be able to fire as long as they are under the Ruiner's effect.

However, Yuri's ingenious invention goes deeper than that. Anyone infected with the Ruiner's chemical becomes a catalyst, spreading the effect further to anyone that comes close by, making entire squads powerless. To prevent his own Brutes from falling victim to this effect in combat, Yuri has altered them to make them immune to the Amnesia Ray completely, making the Ruiner their excellent support. Unlike the other units, Ruiners are deployed with a support power by one of the Synthesis Vaults.[1]


AI behavior

The AI will deploy a Ruiner automatically when it is off cooldown. Only Normal and Hard AI will create Ruiners. Any created Ruiners will target any nearby enemy infantry.


Watch out for these Ruiners, they use psychic rays to stop our troops from firing!
