The game runs smoothly and ha reasonable hardware requirements. It has an impressive number of 3D objects. Apart from the terrain and the units your screen will be loaded with a great number of trees, buildings, birds and animals. Try to fire a grenade from a tank ad then zoom it in. It's realy great.
Lighting effects are equally good from machine-gum fire to big explosions.
These effects made the artillery my favorite weapons. The game has a lot of great effects, still not too much. Nothing has been overdone. The sound is normal, nothing too special. The units closer to you will be louder.
