Serious Sam: Siberian Mayhem || Chapter One: A Smell of Petroleum || No Commentary

In this mission of Serious Sam: Siberian Mayhem, we pick up right after the events of "The Package." Sam's just made his great escape from the Thunderbird oil rig with a boat, and now he’s landed on the frigid northern coast of Russia. His mission? Make it to Tunguska, take down General Brand—who’s now in possession of the Holy Grail—and shut down the portal Mental's forces are using to invade Earth.

Once Sam hits the mainland, he tries to radio HQ for backup... but no luck. So of course, it’s time to go full badass mode. He heads into the Thunderbird Oil Refinery and stumbles across a survivor trapped in the communications tower, sending out a desperate SOS. Let’s see how Sam handles it.
