Destroy destroy destroy
the game it self has its own chain of advancements, or anhancements, aka technology.
you have 3 choices, 1: start the missons, or campaign.
2:start a multiplayer game with friends.
3:play agaisnt the computer, and thats were the fun starts, there 3 levels of difficulty, obvisously easy, medium or hard.
after you choose all your game settings, Eg, map, difficulty, etc..
you start off with a commander, nothing else (note this is in vs the computer) and the plot is simple, build enegy and metal makers for energy to build your standed building then create an army of units and send them in to destroy ever thing that moves...
evan though the game was created wile back, it still keeps up with the graphics, with its own 3d view (so i say) and the sound, and gameplay are all out of this world, literally :P...
