You have 3 days to obtain Big Boss rating in Metal Gear Solid 1's free-to-play period on Steam

Sniper Wolf taunts Solid Snake, who is strapped to a torture table.

I fulfilled a childhood ambition over the past week: I finally got the notoriously elusive Big Boss rating at the end of Metal Gear Solid 1, a feat I've simultaneously been drawn toward and terrified by ever since I first played the game on my PS1 in 1998. How did I do it? Stick-to-itiveness, gumption, and raw skill.

Also, cheating. I played the much easier Japanese version of the game and exploited a couple of speedrunning skips in order to hasten my progress. Hey, it counts.
