This is Epic Game, it has lots of levels and pickups to find, make sure you grab them, they'll give you a big chance to gain on your opponent if he/she is winning.
Dont feel like playing with a friend?
Epic game has an AI feature, allowing you to play against the computer, watch out though because the AI is completely random, you might find yourself dead before you've made the first hit. ;)
