Patch 2.5 for Robot Entertainment’s Orcs Must Die! Unchained, appropriately titled Chaos Theory, makes so many changes to the game that even a five-minute video from the community manager doesn’t begin to scratch the surface of it all. But scratch we shall do.
First of all, there’s a progress wipe. Once you’ve gotten over that, you can hop in and try the new hero, Zoey, The Chaotic Apprentice, whose unpredictable magic requires a high skill level to master.
Warcamps are being renamed to minion portals.
Cliffside Clash is the default PvE map, though the other maps can still be chosen in custom games. Other changes, including random heroes during Hero Roulette and random loot drops.
Hero progress is now measured in levels and experience, and not wins, with coin bonuses and heroic dyes coming at various levels.
There’s a new radial communication menu, letting you quickly shout out instructions to your teammates. No, there’s isn’t a “Stop feeding, noob” instruction.
There are a lot of UI changes and other quality-of-life improvements in the patch, so if you want to do more scratching you can read the full patch notes here.
