so, it's a FPS(first person shooter) which means you view the game as if you were the guy with the gun....
you basically run around in circles and shoot people(or mongeese) in the face with various types of weapons and attachments....sometimes when you die, you can drop a grenade to take out anyone who runs near your corpse
at the end of the round, the person with the most kills is announced the winner and gets to tell all of his friend that he won the prize...which is more attachments....
