Gigantic Sword
Apocalypse's staff turns into a gigantic sword. When active, Apocalypse's melee attack deals extra damage and covers extra range.
Four Horsemen
Summon four hologram horsemen who stampede in a straight line, damaging enemies they pass through and leaving a trail that slows and damages enemies.
Discharge Soul
Fires a projectile that damages, EMPs, and slows. Charges do not refresh with time. Collect charges by kneeling next to tombstones that appear near fallen friendly troopers.
Armageddon
A pool of light marks a safe zone surrounding Apocalypse as meteors fall from the sky in a wide radius around the safe zone. Meteors damage allies as well as enemies, but damage to allies is reduced and non-lethal.
