It's a really cool effect when an Imperium heavy turret comes into view that was obscured in the fog ahead. Those little touches add a lot to the atmosphere of the game. The music and sound effects complete the atmosphere of Uprising . Infantry scream when hit and frequently call out messages to you. Laser fire has it's own characteristic sound and is different for each type of unit.
Explosions are loud and thunderous, especially when buildings are destroyed.
Uprising has some of the best sound effects I've heard. The background music is also good, with a variety of tracks that play for each mission. The main strike against this game is that you need a high-horsepower machine to enjoy it thoroughly. I wouldn't even think of installing Uprising on the minimum level machine the publisher recommends. It would be unplayable.
