 =====Big Boss PS2/HDC Route=====
+Big Boss can be played on the PS2 port of Metal Gear (1987) which was included on disc 2 of Metal Gear Solid 3: Subsistence. Additionally, it is playable on PSTV/PS Vita, and modern consoles that can play the HD collection version of Metal Gear Solid 3. The game is also available on PC via a release on GOG.
 The goal is to beat the game as fast as possible while having the "Big Boss" rank on the final score screen.

+====BEFORE YOU RUN====
+There is an aspect of RNG manipulation in this speedrun. To make your life easier when running Big Boss, you should always launch Metal Gear from the Metal Gear Solid 3 menu (the main selection menu) into Metal Gear, then start with a new game run on original difficulty. This way, your RNG seed will be set to zero. If you continue and reset, make sure to quit out fully back into the Metal Gear Solid 3 menu, then back into the Metal Gear menu to reset that RNG seed back to 0. Throughout the run there will be multiple pointers where you can tell that you are on the ideal seed. The goal is to make the four hoursemen encounter in Building 1 more predictible and hence make it easier to preserver your health.
