Stardate 20X6 is a set of eight Boom-compatible maps released by Zachary Stephens (Ribbiks) in 2013. The WAD is notable for its use of the colour purple, which replaces many of the green colours in the palette. Development started at the end of 2012, continuing for six months until it was uploaded to the idgames archive on 2 June, 2013. The WAD received one of the 20th Annual Cacowards.
A sequel, Stardate 20X7, was released in May 2017.
