My favorite surprise of Nintendo's indie showcase was the announcement of Axiom Verge 2, which is slated to hit Switch and as yet unnamed other platforms in fall 2020. Once again developed by one-man-studio Thomas Happ, the game doesn't focus on Trace, the lost scientist from the original game. Instead you play as Indra, a tech billionaire who stumbles upon an alternate dimension in a cargo lift in Antarctica. She discovers the ruins of an ancient civilization in this alternate world, and perhaps some secrets that are better left uncovered.
Happ and his Metroidvania tribute is one of the great success stories of indie gaming. Working completely alone, and while caring for his severely disabled son, Happ pieced Axiom Verge together over the course of 5 years of nights and weekends. Axiom Verge is an indie masterpiece of game design and twisty, morally ambiguous storytelling. I know I'm fanboying here but I'm pretty happy that we're getting a sequel so soon.
