Sam appears in a quiet town in medieval Poland, near a large castle that contains an important item, the Book of Wisdom, which has the location of the key to activate the backup spaceship, the Holy Grail. Sam kills the creature and enters the second and final portal. After gaining access by finding the three tablets scattered in various yards, Sam discovers that the area is guarded by one of Mental's monstrosities an Exotech Larva. As he makes progress through the city's complex, NETRICSA discovers a very likely location for the teleport the Tower of Babel. Much like in Mesoamerica, Sam fights through temples and villages to find it. The teleport sends Sam to the Babylonian city of Persepolis in ancient Mesopotamia, where he must find the teleporter there. Mental's forces attempt to intervene, but Sam manages to best Kukulkán in battle, allowing Sam access to the teleporter. However, it is guarded by the Mayan wind god, Kukulkán, who doesn't recognize Sam and fights him in order for Sam to prove his worth in using the teleporter. Sam travels through the capital city and the challenging “trials” under the city, and finally manages to get to the teleport. With this in hand, he heads to the ancient city of Teotihuacan while fighting more of Mental's forces. After fighting through a few temples, Sam discovers the key a crystal skull. Sam starts his travels through Mesoamerica in order to find the key that leads to the Mesoamerica's portal. As the ship is located in a different time period, the Sirians had a solution to the problem, they placed several time portals with each major civilization on Earth so that the time portals would send sometime forward in time to the same time period that the ship is in. However, Sam is not trapped NETRICSA discovers a backup spaceship that the Sirians left on Earth just in case something happened to the SSS Centerprice. Suddenly, a crate bus piloted by Croteam Heads collides with the spaceship, causing it to fall back down to Earth and crash into Sierra Madre de Chiapas, a mountain range in Central America.Īccording to NETRICSA, they have landed in the Mayan city of Palenque, in the pre-Columbian era. After the events of The First Encounter, Serious Sam is seen traveling through space in the SSS Centerprice.
