Risk of Rain is a 2013 platform game developed by Hopoo Games and published by Chucklefish. The game, initially made by a two-student team from the University of Washington using the GameMaker engine, was funded through Kickstarter before being released on Microsoft Windows in November 2013. Ports for OS X and Linux versions were released a year later, with consoles versions being released in the later half of the 2010s. In Risk of Rain, players control the survivor of a space freighter crash on a strange planet. Players attempt to survive by killing monsters and collecting items that can boost their offensive and defensive abilities. The game features a difficulty scale that increases with time, requiring the player to choose between spending time building experience and completing levels quickly before the monsters become more difficult. The game supports up to ten cooperative players in online play and up to two players in local play. A sequel, Risk of Rain 2, was released in August 2020, while a remastered version of the game is scheduled for a 2023 release on Windows and Nintendo Switch under the title Risk of Rain Returns.
