To celebrate the upcoming launch of Halo Wars 2, Microsoft is bringing a training mini-game to Twitter direct messages, which will allow players to "compete" with Halo Wars 2's A.I. — Isabel.

Xbox and 343i partnered with Twitter, twofifteenmccann and Emerging Media Technologies to build the mini-game, which will play out in a war of wits in direct messages with a bot designed to mimic Isabel from Halo Wars 2.

The game plays out via Twitter cards sent in DM, which are sadly incompatible with the Windows 10 version of the app — you can, however, join in via the web. Follow @ISA1307_2 on Twitter and tap one of her replies to jump into battle early.
