Castle Doombad Gets Dr. Lord Evilstein's Slaycation Update, with Giant Boulder of Death Crossover

Adult Swim Games' take on tower defense, Castle Doombad, has gotten a major content update, as originally demoed at GDC. This "Slaycation" update takes Doctor Lord Evilstein's princess-nabbing and hero-exterminating antics to a tropical locale, where he must now protect two princesses from heroes who dare to trifle with him.

There are fifteen new stages, along with three new power-ups, one of which being the giant boulder of death from, well, Giant Boulder of Death. Summon this trap and tilt horizontally to roll over those pesky invading heroes. The free update is available now.
