The two multiplayer modes include Hell on Wheels, where players must help their demonic forces escort a wagon into the enemy base, while preventing rival players from doing the same to them, and Survival, a Co-op mode where demons protect their own unit from incoming heroes.
Other additions include runes with different powers, new ways to customize and evolve Báal-Abaddon, and new game settings options that allow easier management of heroes’ ladders.
Impire is on sale for a week in conjunction with the free update.
