The evil Mental is using time-travel technology to warp Ancient Egypt and Rome into his own wicked vision. Only one man has the guts to travel back in time to correct things one bullet at a time--Serious Sam. Now, all the madness from the Serious Sam series comes to the Game Boy Advance for the first time with a new story, new levels, and new enemies. As Sam, you'll have an arsenal of 10 different weapons to help you take out not only Mental's minions, but also your friends in four-player deathmatch action.
