Only the hardest of hardcore PS Vita fans will have heard of the incredibly awkwardly named EXSTETRA.

This is a turn-based RPG from 2013, which was only released in Japan on Sony's aforementioned handheld.

It's notable because both its plot and its gameplay revolve around kissing girls.

Giving your gradually expanding party of waifus a smooch allows protagonist Ryoma to share an all-important energy with them, powering them up so they can defeat the world's monstrous enemies. Obviously.

EXSTETRA is coming west for the first time this summer; it's launching for PC via Steam on the 30th July. A PS5 remaster is also in development, but that version doesn't have a confirmed date just yet.
