Update: It looks like the store listing for #IDARB may have been posted a bit early. Currently the developers are looking for players to help test, particularly the cross-play with Xbox One gamers.
Windows 10 PC gamers can now download and play their own version of #IDARB, the 8-player eSport jetpack arena ball game from developer Other Ocean that was released for the Xbox One in 2015. Windows 10 gamers will be able to play against Xbox One players online thanks to the game's cross-platform multiplayer support.
The game does require Windows 10 users have an Xbox Live account to play, and it also requires a Xbox compatible controller. Here's the quick description:
Built with the input of thousands of crazed internet gamers, #IDARB is a chaotic 8-player eSport jumping future arena ball game. Create characters, teams, team logos, tournaments, even your theme music, in this highly customizable experience complete with disruptive "hashbombs" which dynamically change the game itself via Twitch and Twitter! IDARB supports up to a whopping 8 simultaneous local players, and up to 4 vs. 4, head-to-head online matches. Additional features include a mind-blowing single-player story mode, wild half time competitions, and unlockable recipes."
