Playstation 2: Serious Sam Next Encounter

Serious Sam: Next Encounter starts off with Sam Stone stepping into a time machine which teleports him into Ancient Rome where large groups of Mental's forces are waiting. Sam has to confront not only the armies of his enemy, but also the Mini Sam, an evil being created by Mental. The story takes Sam through three different settings of Earth's past: Ancient Rome, Ancient China and long lost Atlantis where Sam, as usual, has to wipe out the hybrid army of his nemesis and save the timeline from corruption. On his way through Rome and China, Sam defeats other two Mental's timelock guardians: the gigantic beast Diablotaur and the monstrous Subterranean Emperor Hydra. The game culminates on board of a Sirian mothership, where Sam has to battle the Sirian Dark Lord, a soul of a great Sirian warrior infused with a giant robotic body.
