After a wave of mean-looking guys, you're given a couple minutes to regroup and reassess, and then you're back to shooting mean-looking guys. This repeats until you finish the set amount of shooting mean-looking guys on the server. After that, it's victory and then you move onto shooting mean-looking guys on different servers. It's simple, blunt, and very frank, and there's an honest intensity in that. For a paltry $20, you will not be going wrong with this purchase."
