Why hasn't this been guessed yet?
#29: Hints: Your arch nemesis sets up a trap for you again. You fight him and his army, that is literally not from this world with a machine that looks like a household appliance.
This machine was build by one of your friends who also made a bunch of other inventions, one of which in particular was questionable because it lead to alot of bad stuff happening in another only loosely related game where neither the protagonist of this game nor the guy who invented all of this stuff show up but a different iteration of the villain of this game does.
This game is part of a series that already showed up on my list.
