Most games which have full 3D world are extremely slow and lagged. But this one is smooth, with an excellent frame rate imitating reality superbly. Through the game you get to play on more than 5 different planets, each with its own atmosphere, terrain, gravity all of which make the game so fun and interesting to play. Weapons fire well, the ammunition can be clearly seen and defined flying through the air. This is great stuff, especially if you think of the weapons in other combat games looking like plain yellow lines flying all over - dull and boring.
Explosions are realistic.
The game takes a vastly different approach from the usual big pile of fire and then ashes style. You can see when a vehicle is damaged, and the explosion is a more serene effect, with a couple of small explosions causing debris to gallop through the air. Overall, graphics are smooth, assured, and as close to the real thing as any game has gotten yet. Sound - this too gets full marks. The game itself has a great soundtrack - pretty much like those futuristic war movies made nowadays.
