I actually quite enjoyed Space Monkeys (assigning different players to different Perk machines), Gas Zombies and Phasing Zombies (especially since you can completely avoid them and they are easy to fight in low gravity, why would you even go in the labs during a round other than to do the easter egg?), George and the Hellhounds. The Thief round is one of my favourite moments from Zombies.

The Astronaut Zombies were annoying but if you just leave them as if they were George, they don't get any extra health so you'll be in luck if you find yourself trapped.
