Yes, you don't have to tell me, it is very simple. But that doesn't matter... it is very fun and original.
Everyone spawns up top in one of those baskets on The Pit. They have energy swords, but these are usually just for show.
The point of the game is to kill eachother. But there is a catch. There are oddballs in this basket, and if you touch one, you pick it up.
You lose points for touching the oddball.
So, you have to "dribble" the oddball around by tapping the left trigger, and then use the oddball (or your sword) to punch out other players. It is really fun, and frustrating at times (especially mid-lunge when you pick up the oddball), but it works well.
Below are some pictures.
This is the dribbling technique:
This last one is an overview (well, underview) of where we are in the map. The whole map takes place in that basket.
