Frozen Tundra mod for Half-Life 2: Episode Two

Frozen Tundra is a modification for the critically acclaimed first person shooter Half-Life 2. In the mod, the protagonist finds himself lying on his back besides a wrecked helicopter, in the middle of a snowstorm, not remembering how he got there. Wounded, he staggers around until he finds shelter in what seem to be an abandoned facility, where he searches for a way to summon rescue. However, it doesn't take long before he finds himself surrounded by hostile soldiers, who don't seem to be interested in capturing him alive. Sneak to avoid contact, solve puzzles, manage your way through the harsh climate to survive, and ultimately find a way back to civilization.
