dark… darker yet darker… they come from the void… the darkness keeps growing… spreading… comsuming…. the shadows cutting deeper…. shreading reality…

UND_RT_LE is a Game Virus AU I thought of with Gaster as the antagonist of this AU. This is set at the 2nd reset of the player’s game.

Sunk so deep in his despair, he made a goal to take the world with him down to zero. Thus he became something like a virus that slowly corrupts the game from the inner most files. The lesser viruses are horrifying beings created by Gaster to act as BUGS that eat or corrupt the characters and the environment. This affects other players as well but not Frisk through their strong determination. The whole underground is losing form and color, becoming black and white and block-ish (something similar to the game Transistor). Even the music and speech and names are missing parts. The corrupted characters is like encountering amalgamates and the only way to slow down the process is to SAVE like in Asriel’s battle BEFORE they become 100% corrupted otherwise they are a lost cause. Reseting wont change the fact that the game is corrupting. To cure the virus is to either fight Gaster or talk to him….. or is it?

It is just a basic concept i thought out thinking “I want Gaster as a bad guy…” and I have not delve deeper into it yet…. character concepts may come later or soon?
