Last year, Nintendo fans finally found Luigi in Super Mario 64, after the source code of the game was leaked online.
Now, a Sega fan has found Luigi somewhere even more unexpected – in a previously-unseen development build of Dreamcast racer Sega GT.
Luigi can be seen holding a stopwatch and chequered flag in one of the game’s levels, apparently as a joke temporarily put in by developers before the game was finalised and shipped to the public.
