It's the sloppiest award-winning game, and the poorest performing shooter we've seen on current generation consoles. PUBG does not work well on consoles at all in its current state and needs another year in the oven. Even the little things, like basic matchmaking problems with friends or typos in the menus, aren't addressed.
Getting in and out of vehicles are two separate buttons and if you want to pick up a specific item from a pile of loot on the ground or move mods from one weapon to another, you better hide yourself for a few minutes. Sometimes it won't even work unless it's tapped perfectly. Inexplicable, holding down the trigger instead just slightly tightens the crosshair (it does the same on PC). Aiming down sites isn't holding down the left trigger, it's tapping it. Performance aside, PUBG is simply a bad 'shooter' with an awful control scheme on Xbox. Reloading a weapon for instance in the heat of battle requires players to hold down the 'X' button instead of just pressing it quickly.
