OnePlus has partnered with AirConsole to create an online gaming system. These games are exclusively made for OnePlus in partnership with AirConsole.
The Airconsole section in the OnePlus site reveals something about AirConsole games for its OnePlus phones:
It reads: YOUR BROWSER IS THE CONSOLE.
DEVICE IS THE GAMEPAD
In order to play AirConsole games on OnePlus phone, users need to open the browser in their OnPleus mobile phones. They have to then open www.airconsole.com on their browser. They alternatively need also to log on to the website on their laptop or Desktops and enter a code that is displayed there on to their mobile browsers. After entering the code onto the AirConsole section on their website, they can play the games on their PC and use their OnePlus mobile phones like a gaming console.
This is another way for OnePlus to target the gaming population. It is also intended at a non-gaming audience. It seems like OnePlus is targeting users who might not use a PlayStation or Xbox but will rather prefer to play games using their OnePlus devices.
