The game's visuals were very nice for a game like Massive Assault, and they are only improved in Massive Assault Network. As I said in my Massive Assault review, the terrain and water look fantastic. The vehicles look great, are easy to recognize and easy to tell apart. The weapon effects and explosions are excellent. A battlefield that was once quiet and still while you were thinking about your strategy suddenly comes alive in missile fire and explosions as you begin making attacks.
The interface is equally impressive. It's very easy to make the interface for a strategy game cumbersome and hard to use. However, Massive Assault's interface is clean, streamlined, and just plain old perfect. Aside from when I was riding the usual learning curve, I was never confused by what I saw onscreen. The interface is a tiny bit clunkier for some online components. One has to go into the main menu to do things like send messages and such, rather than just having them built into the game's HUD.
The music of Massive Assault Network isn't going to win any awards, but it works well for this game. I've said that the true test of a game's music comes down to one simple fact. Does the player leave it on or turn it off? Well, I still don't turn this one's off.
