Sam is back in the all-new second episode of his battles with his arch-enemy, Mental. After hijacking a Sirian spacecraft in ancient Egypt, Sam "Serious" Stone crash lands in the South American mountains surrounded by an even stronger army of Mental's evil forces. Sam may have new enemies, but he also has three new weapons to stop them, including the flamethrower, sniper rifle, and chainsaw. Serious Sam: The Second Encounter also features new power-ups, which you'll need to overcome enemies in both single-player adventures and multiplayer deathmatches.
