UMAG is a game that you can play in different modes. You can play single player to get the feel of the game and how to weapons work. You can also join or create a private game online, or a vs. game against another online player. Once you get confident, you can join a four player ranked game with other online players. Toggle through the weapons by clicking on them; they're on the bottom of your screen. Every weapon has a different power and the screen to the right should tell you how it works. Once you're comfortable, join a game to get the feel of gameplay. Good luck and have fun playing UMAG!
