Tower Assault retains the great action of the first game while multiplying the suspense tenfold, via great sound effects and level design. While the game is fun in single player mode, its' the multiplayer mode that is the real star of the show. The first player co-operates with the second player taking the role of Nash, the rookie who is killed at landing in the single player game. You both share a single screen unable to move far enough apart as two be on different screens, but the scale of the game means this is not a problem. It might initially seem that this option would make the game easier, but there is still only the same amount of ammo, and it must be divided between two players. This can stretch the co-operative feeling in the game, as players can often find themselves fighting for the pick-ups rather than dividing them fairly. It was probably with this in mind that the designers made it so that your bullets couldn't hurt the other player. Playing with a friend doesn't make the game easier, but is still a great experience especially if you are tired of kill-them-all deathmatch games.
Overall, Tower Assault improves upon its predecessor in every respect-- gameplay, graphics, and level design. It's also much more difficult this time around, so anyone new to the genre should be prepared to meet a frustratingly endless horde of aliens. Two thumbs up!
