You can use shields and jetpacks in this China-only PUBG Mobile
It’s not Fortnite, but the alternate PUBG Mobile for China allows you to build a few things

China loves PlayerUnknown’s Battlegrounds so much that there are actually two versions of the game on smartphones, exclusively for the country: Exhilarating Battlefield and Army Attack.

So what’s the difference? Well, uh, for a while there really wasn’t much difference at all. They were developed by separate studios and had slightly different button placement, but that was about it.
But turns out, it’s not as intense as in Fortnite. In that game, you get pieces -- walls, slopes, floors -- that you assemble into structures. But in Army Attack, items are ready-built and scattered around like normal loot, and all you need to do is tap to deploy them in battle.

It’s absolutely helpful, but there’s a catch: It’s a little slow to unfold and recycle (yes, you can put it back in your bag after using it once), and you have to drop your weapon when doing it.
