Oshiro Project:RE, often rendered as Shiro Project:RE and abbreviated as ShiroPro:RE (城プロRE), is a mobile and browser-based tower defense game made by DMM Games. A Kantai Collection-styled game where players control "castle girls" - or moe personifications of forts/castles/historical buildings (mostly from Japan, but including some international representation).
Originally launching in November 2014 (with a title rename the month prior), the game would be temporarily closed for mechanical renewal and overhaul in April 2015. It would re-open in March 2016, with its current title, gameplay mechanics and sprites being largely overhauled, and certain girls either being removed or having had their art changed.
