Starting today, May 22nd, and lasting the entire weekend, until May 24th
the epic unit Ruiner is guaranteed after 40 Specialist Beacons have been used for recruitment during this event.

Ruiner is an Epic Marauder Chemical Debuffer
and specialized anti-repair unit, afflicting his enemies with inferno and repair-reduction, and anyone who dares repair with bombs.
Deal with the pesky repairing supporters with some glorious explosions.

Additionally, Ruiner is currently a part of the Centurion Fusion event

Good luck, Commanders!
