Welcome to the North Atlantic. You've been locked up in a car on a train careening across the ocean, your head kept swimming in a digital malaise of Combine brainwashing. However, for some reason, you've been released from confinement, and someone named Rainman has decided that you will be his weapon of choice in dismantling a massive Combine installation on a remote volcanic island. Making your escape from the train, you begin a one-soldier guerrilla war against the Combine. Find whatever supplies you can get your hands on, keep moving, and stay alive. This base isn't going to destroy itself!
