Hey guys, i remember about an old game that you were controling a blue ozn above a blue building initialy (you could move the ship across the map, but if the ship was destroyed the ship would be respawned at the top of the blue buiding) the only goal of the game was to destroy the enemies building (green color) that had the same ship as yours (green color), in the game you could capture other building by destroying them, these building could have benn used for making units(tanks,flamethorower,anti-air units,robots,{aircrafts[in the top left corner]}),other helped you get more resources & energy.
Your ship and the enemies ship could destroy other units, capture buildings,destroy each other,and if you tried to destroy the enemies main building with your ship, the building would destroy it by a beam of light.
The game was from about 2000,for PC, the grafic was 2D,and the camera angle was from up->down,you couldn't change it,but it would move(the camera didn't had a full view over the map,but a medium size space)
