Tencent promises a similar PUBG experience on mobile as on PC, although it remains to be seen how the company will translate the shooter to a smaller screen. (There are plenty of battle royale-style games already on mobile that may give fans an idea of what to expect, at least.)
The game is currently planned to launch in China first, although Tencent neither gave a release date nor detailed plans to expand to other markets. But as the company pointed out in its (Chinese-language) press release, PUBG has sold more than 20 million copies worldwide — so we’d expect a Western release at some point.
Also, according to unofficial information, we know that the differences between the mobile version of the game and the computer will be insignificant, and the mechanics of the game will remain untouched. The release of the game is scheduled for 2018.
