You were exploring a Russian forest during the winter. Why? I dunno, maybe it was the strangely melancholic vibe that the place gave off. Before long, you saw a....skeleton sitting by himself on a cliff edge? Upon closer inspection, he seems to be a robot that was made to resemble one (given his tall and lean frame...he certainly archives that). The Robot Master was seemingly just thinking about life, before he notices you, as he points his arm at you, collapsing his hand and revealing a hidden machine gun in his forearm, now directly pointing at you. What have you gotten yourself into? State your intensions.
