This game is unbelievably hard! Jesus Cristo.... You get damaged by zombies waaaaaaay too easily, and you don't have the health to deal with it. Cool concept, good look, terrible gameplay.
Wait, can someone tell me why this game is so highly ranked? It's just pointing and clicking. No strategy, no thought: just carpel tunnel. 1/5 Terrible, boring game.
Okay, here's how you beat the roach Gregor: Load up on Disrupt (4 of them) and hit him with a disrupt every round while your friends hit him. If you're lucky, Roald will stun him once or twice and you can hit Gregor for big damage. Other than that, be paitent and stay the course.
