Hardmode Underverse Massacre completed - Roblox Sans Multiverse

Game link: https://www.roblox.com/games/11383378... In total this took me 3 hours, although it should've been less. And, yes, if you die, you have to redo ALL the previous bosses again, unless you get to the final boss (but if you leave the game, then it'll probably not save and you will have to do the 7 bosses before it once again) The entire difficulty comes purely from X Chara and Shattered Dream (though, the very first attempts at him, I could easily defeat Dream and thought he was one of the easiest, then for some reason after I first beat Reaper Chara, I would always die at Shattered Dream, so I don't know what happened there). Dust and Gaster are a piece of cake, I think I managed to even first try them, lol. Reaper Chara took me way too long to realize that the entire fight is simply survival (when I did, I have never died to them ever again). Died once on Error, because didn't know what his attacks are, same with Fatal Error. Final Error 404 on the other hand... He's not necessarily hard by himself, but the LAG he gives you at the end is INSANE. Literally thought my pc's gonna crash, because sometimes the screen would freeze for multiple seconds. I really hope the creator will fix this optimization issue, because it genuinely might crash people who have a not so good pc, mobile users FOR SURE. The drop is ERROR SOUL SWORD, which does 3 million damage and is an auto-aim weapon, making this entire challenge worth the grind. (kids are about to spam the game's group wall asking for a nerf, because they can't get past Dust or something, mark my words) 0:00 - Location 1:32 - X Chara drop 2:03 - Reaper Chara drop 2:21 - Completion 10:41 - Final Error 404 15:50 - Weapon showcase
