Ronin is a turn-based action platform video game developed by indie developer Tomasz Waclawek and published by Devolver Digital. It was released for Microsoft Windows on 27 May 2015 into Steam Early Access and left it on 30 June 2015. A later update for the game introduced builds for OS X and Linux on 15 October 2015. A PlayStation 4 port of Ronin was released on 1 November 2016. Ronin has a stealth-based business complex level design which the designer Tomasz Waclawek described as a rip-off from Tom Francis' Gunpoint. The player needs to avoid being seen by the guards and use the surprise moment for silent kills. Once in a fight situation the player has to dodge the guards' attacks and get the right angle to defeat them. The player can also throw their sword at enemies.
