Metroid: Federation at War for Forces of Corruption allows players to chose to play as either the Galactic Federation with Bounty Hunter Samus Aran and Commander Adam Malkovich or play as the Space Pirates with the Evil Phazon being Dark Samus and Geoform 187, Meta-Ridley.
The Space map for Phaaze. Used an ocean planet since it's the only blue planet in game.
With a little tinkering with the lighting, you could make it look more like Phaaze.
Looks pretty good. Very blue. Blue is very important for Phazon related things. XD
Maybe you should try to create a 'wormhole' near where the attacking team starts, to make it look like Prime 3. (I know, in the game it only opened and closed when the Leviathons created it.) There's a black hole prop that might look nice. You could even make another one by the Pirate Homeworld to show the link there. Just a suggestion, it could also turn out terrible.
Alreay have a blackhole/wormhole added, but I didn't add it in myself. This map was edited from another map and it already had a blackhole. Didn't notice until after I created the map.
