Just a random idea that popped into my head.
The concept of the PC's have to defend an area against a theoretically infinite # of enemy. Armies of orcs or zombies.
Sort of like a swarm. Any hit on an individual enemy would drop them, with a constant flow of new enemies. You'd track total hp dealt to decide when the enemy stops.
X# enemies show every Y# rounds.
Maybe a boss type shows after enough hp damage dealt.
