2. Spam The Sniper Rifle
In GTA Online, a variety of weapons are unlocked as you progress through the levels. Initially, you will start off with comparative pea shooters like the handgun, but later, once you start hitting levels 90 and above, Ammunation will start stocking heavier artillery. At level 90, players can get hold of the sniper rifle and royally irk all their opponents by hiding up a ladder somewhere pointing their scope at a rival from a nice and safe distance. Snipers are difficult to kill even when you know where they are, let alone when you're wandering around in blissful ignorance unaware you're being stalked by someone's laser dot. This can become particularly bothersome when players start spamming the sniper rifle tucked away up on a vantage point instead of taking to the streets like everyone else.
