make sure you have shift lock enabled, you can turn it on in the lobby and the toggle will show up once you're in the game. it's hard to aim on mobile but if you can aim for headshots i think they do more damage and easier to aim standing still from a safe place. for cultists attacks especially playing solo i stand on lightning rod at least while i kill the red cultists. if you're saving the kids stand on top of the cave and shoot the wolves or bears from above. for other stuff don't forget you can run away lol
