Adding a factor of weather might be interseting.

Iricia: Blizzard every now and then. Deals X amount of HP and completely destroys all vehicles. Escape it by running indoors.

Gwars: Remake the map a little to add a volcano. The volcano erupts once/match which is determined by how many players are in the match (Example, 3 players in Gwars... Volcano erupts 3 minutes into match, 10 players in Gwars, erupts 6 minutes into match).

And maybe for deathmatch, since its surounded by water... When the time reaches 45 seconds, the entire map but the middle building floods. This would also make matches end for sure...

If anyone has ideas for the other planets please feel free to add them.
