This game fulfills my love for out of bounds shenanigans
Playing through the game for the first time and even though I only just started chapter 3 I've been loving using the game's wonky parkour against it to get out of bounds. Be it hopping over some barbed wire fences, climbing up to unintended platforms or finding the completely wrong way to get an orb drone, it's been a blast.
This most recent one was the best so far. In Chapter 3-2 I thought that one of the sand dunes at start of the checkpoint looked pretty close to the ground so after a few attempts I got P to land out of bounds and just started exploring. Eventually I reached some pillars that looked climbable and ended back in bounds to the end of checkpoint 2 where Metal Gear Rex first pops out. But all that was keeping me from him was a few barbed wire fences, so I shenanigan'd my way over and boarded the boss at the halfway point.
After some trial and error I realized I needed to make my way down Rex's leg to damage his first health segment, but afterwards I proceeded to defeat the boss and skip most of Chapter 3. Still gunna go back and finish the chapter *mostly* legit, but I can't wait to see what other sequence breaking I can do.
And if this sounds like it could be useful for speedrunning let me know and I can show anyone interested in how I did both skips.
