Graphics are top notch,JoWood implemented 3d very well. Terrain is rolling,trees fall when tanks run over them. If a unit explodes near water,flying debris will make a splash. Unit fire is nicely done,lazers and rockets look like what you would think they should when they travel and impact. I have a fairly powerful machine,but at times the frame rate would bog down at 800x600.
Sound effects are good.
If a walker is coming,you can hear its feet pounding the earth before you can see it. The default setting for the music is off,tell you the truth,i never played with it on.
