Take On a New Challenge With The Siege of Castle Doom

Race against time as the Siege Gauge fills, and stop Doctor Doom before he can activate the deadly Cosmic Inductor. Gather Battery Cells and complete challenges to earn defense, damage, or tactical upgrades from a collection of 12 different perks. Choose your path through Castle Doom's winding routes and thoughtfully select buffs to alter your combat abilities to become an unstoppable powerhouse.

Whichever path you take and perks you choose, be sure to reach Victor von Doom before the ominous Siege Gauge is full; the castle's forces grow in power as the gauge fills… Permanently unlock new equipment and events from Reed's Lab after each run, as well as modifiers that will deepen the challenge and potential rewards you'll encounter in your future attempts.
