An open beta for Microsoft’s Halo Wars 2 will begin on June 13th, the same day as Microsoft’s E3 2016 presentation, according to an Xbox One product page for the game.
The product page, spotted by Mondo Xbox, states that the real-time strategy game will run its multiplayer beta for a week. It only mentions the Xbox One for the beta; there is no word on a similar test for the PC. There is also no mention of what the beta consists of.
Halo Wars 2 will be released in the fall for the Xbox One and PC.
