I haven't tried out the game yet and I definitly can't wait for the CO-op to come out in a month but i could see adding more people to the group would be a bit more fun. Kind of like playing left for dead 2 with a 4 person team snaping up zombies. I'm hoping for more content & extras will come out in a later time for more fun and wanting to see this game grow. Even being small indie game makers, i have hopes! Sometimes small indie gamers see what is needed than Big game makers like EA etc :)
