World War Z: Aftermath
Zombies are pathfinding scripts, not minds
Variance2 vs 3
World War Z: Aftermath leans a little harder on variance, though the gap is small.
BioShock 2
Sister-gathering waves add randomness.
World War Z: Aftermath
Spawn director shuffles hordes mildly between runs
Optimization5 vs 5
