History ThatOneBoss / StealthBasedGame

** Metal Gear REX itself is a pain in the ass, especially if you try to fight it from a distance in the original release on [[UsefulNotes/PlayStation the original PlayStation]]. It's anti-tank rockets will ''home in on you'' unless you use Chaff Grenades, which will also knock out your radar for a short time. Getting too close to it will result in either getting a laser to the face or being stomped on. What really hits this home however is that you fight it ''twice'': in the first fight against REX your target is the Radome on its left side, and the second time you face it you need to aim at [[spoiler:Liquid]].

** Two Face as the BonusBoss in Arkham City. The player uses Catwoman (who has a '''lot less health than Batman''') and needs to hide from an infinite spawn of mooks while trying to use a silent takedown on Dent. Only, takedowns damage him for 1/5 of his health, and all the mooks will rush to get you once you go loud on him, so the best way to get through it is to use simple strikes after stealthily eliminating all but the last goon near him on the bridge without him noticing so that you can take him down before his aforementioned "infinite mooks" can kill you after eliminating the goon near him on the bridge. (otherwise, might try to catch Harvey alone and away, while dodging his bullets and praying you knock him out before any of the respawning thugs arrive to his aid)
