Runbow pits up to nine players against one another online in variety of game modes that use color to create and destroy platforms in a variety of interesting ways. the general premise can be summed up in the phrase, "if you can't see it, it doesn't exist." Waves of color splash across the screen and the platforms that match the current screen color vanish until the next color sweeps the stage. It's a simple premise, but the execution makes it special.
While up to nine players can play together online at one time, the Switch version of Runbow supports up to eight players in local co-op with the PlayStation 4 supporting four players. Together, players can compete in Run, Arena, or King of the Hill modes in either private games with friends or open your party up to other players from around the world.
Runbow also has a single-player Adventure mode with over 140 different levels that take players on a quest to save Poster District from the villain Satura. A separate challenge mode is available that has players swallowed by a gigantic creature and attempting an escape from the beast's colorful innards. Both modes can be tackled solo or with friends.
The more players splash around in the colorful world of Runbow, the more fun stuff they can unlock. In addition to concept art and costumes, there are 19 unlockable guest characters, including Shovel Knight, CommanderVideo, Shantae, and Lilac.
While Runbow originally released in 2015 on the Wii U and PC (as well as last year in 2017 for Xbox One), the Switch and PlayStation 4 versions have had a bit of a bumpy road to release. The Headup Games and 13AM Games teams have apologized and pushed back the release date that has yet to be specified. The two studios stated that the delay was to spend more time optimizing the game for each respective system. The delay is "just a matter of weeks" according to the developers, so hopefully it doesn't leave too many people flustered.
