the game type is in my file share on bungie, but all you need to change is make the movement to 90% and the gravity to @00%. you need to finish the map with 2 of each grenade type. it is my first map of any decency and I spent a lot of time on it so please post what you think of it.

(Edit): added pics and discription.

this map consists of5-6 levels, each with a different challenge. throughout the map there are 4 grenades on iinstant respawn that you need to pick up to win. it resembles the map "Miles" but my own version of it. I would say it is just as hard, but also possible, to do as Miles.
