Suddenly I remember MMO game that I ever played with my friend like......4-6 years ago, I want to play it but I forget the name...also there's chance that game no more exist, but maybe you guys can help me out ?

the game setting that I remember
-something about galaxy
-after we create account we can choose the races (human, alien, etc)
-we also can choose weapon tech (nano, traditional, alien weapon, etc)
-I choose human so my super trooper named Super NID attack/defend soldier
-we can have...mothership
-for some turns, we can find planet
-we can attack & raid another player
-we can have commander (another player that will be our mentor or boss)
that's it...that's some thing I can still remember and write
