Looks like an auto-battler on the surface, but there is plenty of fiddling underneath. Target priority, movement, and survival rules all have a say in how those five characters behave once things get messy. Mixing heroes from wildly different eras also makes team building feel less predictable than it first seems.
The full version is already unlocked, so the entire campaign and later challenges are open to play. Endless mode gives the roster another reason to evolve after the story, while the best moments come from watching a carefully tuned squad finally behave exactly as planned.
