After the apparent success (and speedy sell out) of the retail PS4 release of Retro City Rampage DX from vBlank Entertainment back in November, the company is going for it again with a Vita version. For crazy, fallout shelter collectors like myself this is a great chance to pick up a copy of the game for when servers go offline decades from now. According to the studio's post on the PlayStation Blog, the demand was greater than expected for the PS4 version, but there's no guarantee how available this release will be. If you're interested, I'd suggest diving in now because the last time it sold out in about 24 hours. It really helps that this is a pretty fun game, so there's that.
The retail Vita version is going for $30 and is region free. If you're interested, place your order here: https://fangamer.myshopify.com/products/retro-city-rampage-dx-for-ps-vita
