Super Smash Bros. Ultimate is getting a stage builder mode, according to the blurry corner of a new Nintendo trailer.
Last night, eagle-eyed fans spotted gameplay in the latest Smash trailer was actually from an upcoming build of the game - one which lists the stage builder mode on its main menu.
It's not a huge surprise - Smash Bros. Brawl for Wii and Smash Bros. for Wii U both included the feature, which allows players to construct their own levels using pre-existing objects - but it's something Nintendo has stayed silent on adding so far.
Was this a canny tease or a simple slip-up? We've asked Nintendo for more.
You can watch the trailer in full below - the mode can be glimpsed if you hit pause at the 00:01 second mark:
