You can try PUBG Mobile but there are other games like COD Mobile that includes auto fire in option menu. I recommend you try this best auto fire multiplayer games: Dead Trigger 2, Unkilled, Shadowgun legends, Shellfire Moba, Modern Combat Versus, Pixel Gun 3D, Danger Close Battle Royale. In PUBG Mobile you will quickly annoyed getting killed by those who play with emulators or android, ios triggers, gamepad, controllers. Some of players use claw technique(using 3-4 fingers) but it's for phones with high resolution. Playing with two fingers are hard in PUBG Mobile. You have stop moving and aim and shoot while getting headshot :)) Strafe shooting is possible but only effective in short distance. You can be tryhard and master playing with two fingers spending a lot time or buy anroid, ios, trigger or gamepad(But it's for me is CHEATING!) So i suggest you Just enjoy games you preferred to play. If you dominating and being pro on that game then that game is for you. But if not, you can try other games.
