Now that's a lot of zombies!
I feel like this game is in a kind of ASMR state at the moment lol. It's pretty satisfying to kill the indefinitely massive swarm of zombies, especially with the chain gun.
I'm happy to report that the performance worked quite well, though the framerate was a tad bit slow, but that's definitely just my computer's fault. It seems you have an impressive system going here, no problems on my end. Great work!
