Many people say that Toby Fox used GameMaker to make Undertale, but I'm curious -- which version of GameMaker did he use?

1 Answer 1


Undertale was released on September 2015, while GameMaker 2 was released on March 2017 and GameMaker 1 in November 1999.

It was made with GameMaker 1. Or GameMaker Studio 1 (GMS1) to be more specific, released in May 2012.
