Holy shit, I'm so glad I was wrong! Looks like most of the monsters are actually returning, and I love the fact that Drain Deimos now affect the environment that they live in, like Xenomorphs or similar fantasy creatures. Although I really don't know why they thought adding teeth to the Hunter γ was a good idea, it just makes it look less like a frog and more generic. Oh well, I guess you can't win 'em all :/
Also is it just me, or is Project Resistance looking more and more like Call of Duty Zombies?
