Sekai' Projects' The Labyrinth of Grisaia is coming to PSP and the Vita in Japan next year, but it could also land in the west if this upcoming Kickstarter campaign is successful. The visual novel game, originally on PC, is set in a girl's school where the very first male student has just arrived, causing all sorts of shenanigans.
Certainly, one of the girls has access to a sniper rifle so I'm guessing lover's tiffs are high on the agenda. It is based on an anime currently on Crunchroll, and the game needs $40,000 per episode, with the plan being to get the whole trilogy translated, with physical copies as part of the plan.
This is a neat use of Kickstarter, and I'd like to see more western devs get support for Vita versions this way, beyond the usual indie projects. Seems like the only route left for moderate projects.
