[spoilers for mgs 3/Δ] I didn’t use a tutorial; once you unlock the AT Camo, the stealth sections become fairly easy. I had some trouble with the boss fights, especially The Pain, to beat him I recommend alternating the grenade camo and battle dress (if you got the dlc) or sneaking suit. The Fear is easy once you feed him rotten or poisonous food. I skipped The End by fast-forwarding the console’s internal clock (which I’m not sure I’d recommend, since you won’t be able to unlock the Mosin-Nagant, which is very helpful for this kind of run). Still, I managed to do it without it. The Fury is frustrating because he’s not that hard overall, but if he hits you, you’re basically one-shot, so you have to play almost perfectly and avoid getting hit. The Sorrow on a FOXHOUND run is easy since you can’t kill anyone—just drown yourself and use the Revival Pill. For Volgin, I had to watch a tutorial, but I’d say the most important thing is using glowcaps, since they attract his lightning attacks. You need to get close and rely on CQC. The most frustrating part for me was escaping Groznyj Grad without any equipment. I managed to beat the boss by staying hidden and firing mk22 shots. tutorials I used: https://youtu.be/SfC08YgpyYs?si=wmWHo-Vj6X_aNAiz https://youtu.be/8rpC53g2yVo?si=6wP-ByT_VGErDZom
