You are a lone space marine, the only survivor of the landing force sent down to Stroggos as part of Operation Alien Overlord, the final push against the homeworld of humanity's cyborg nemesis, the Strogg. You wake up and pull yourself out of your landing pod. The distorted screams over the crackling of the radio tell you everything you need to know - the landing was a failure. Somehow, the Strogg knew about the plan. But you've still got a job to do, and your pistol lies before you.
