Cave Story was a charming Metroidvania originally released way back in 2004 as a freeware game. In 2010 it was ported to the Wii and DS in 2010, later to Steam, and now it's coming to the Nintendo Switch.
It's coming as Cave Story+, though, bringing with it seven new play modes, fifteen new levels, ten weapons, twenty boss battles, and four different endings. All shown off with fancy new high res graphics.
That all said, it will set you back, by US pricing, $30 (approx £24). You best get saving, Cave Story+ is out on June 20th.
