All of that... FOR 1 XP!!!
Okay so I kinda love this secret boss battle with Jerry and even though I have no idea what a Metal Gear Solid is I'm glad I got to experience this (I know what it is by the way I've played Smash Bros) Anyway onto the actual description! This is my fandub/gameplay of the amazing game Deltatraveler! I have some questions that I want to answer here so I don't feel bad for not responding to people promptly, so no this isn't a mod and no this isn't an official game by Toby Fox, this is both an Undertale fangame and a Deltarune fangame that crosses over with multiple worlds making this one of my favorite crossover games, the first world this game crosses over with is Earthbound which is actually the game that originally inspired Undertale, but that's not it because one of the other worlds you explore is the world of Underfell which is one of the most popular Undertale AUs in the entire fandom. So this game is set right after Deltarune chapter 2 with Deltarune Chapter 3 still not having a release date this has definitely gotten me through the Deltarune tomorrow phase. One thing I think is really cool is there is an easter egg where you can backtrack in the first section and find Frisk who had just fallen which means this can be placed at the start of Undertale! Another thing this game does really well is the multiple routes as it never feels like you can just stop without consequences, oh I also played the hard mode and I was not expecting a playable Frisk and getting to meet the man who speaks in hands!
