Solo, I enjoy it somewhat but it doesn't hold my attention for long. With a friend or two, though, this game is phenomenal. There is a lot more depth than you'd assume at first glance, with strategies ranging from talking your way through missions to to going full on zombie apocalypse (with you as one of the zombies). The difficulty leans towards hard, but not crazy hard. This can vary depending on the character you choose, how you're trying to win, and which "mutators" you choose to activate. I highly suggest role-playing. My buddies and I got this game with dreams of role-playing as a group of escaped, pissed off gorillas, and the game did not disappoint. We laugh the entire time while toying with various combos and play styles. And get the character pack. It's worth it just for the alien and to support the developer which, to my understanding, is primarily just one guy. I will absolutely be buying Streets of Rogue 2 when it comes out.
