Ok here's the lowdown:
--Uses the Deathvalley AI (included in the map).
--This map is rated at 16 MB, but really, you want to have 128 because with lots of players the unit count soars (and really you should play with 1000 to 1500 units per player, not 500.)
--PLENTY of room to build your base with your ally, and plenty of time to build it.
--Even at max speed, you will have at least 7 minuts before someone can attack you (by air, longer by ground)
--BIG, mostly flat metal map.
--Massive, near continuous hail storms.
--Designed for 5 teams of 2 (1&6, 2&7m 3&8, 4&9, 5&10, using fixed start positions).
--Gracity is only 1/8 normal (14/112), meaning the big guns carry far:  nukes and airstrikes are the way, any ground force will be reduced to wreckage before it can fire a shot.
--EXTREMELY high winds (9000-10000) to make up for the terrible solar and no tidals.
--Best playable with 5 players and a MINIMUM of a 500 limit on units (1000 is ideal for the map size, even more).
--Have fun, DAMN IT!
