Primary weapon selection is the most important thing you need to decide before to play Sidearms.io unblocked at the school. There are pistol, sub-machine gun, revolver, shotgun, assault rifle options. If you’re a long-distance shooter, you should go with SMG or Assault Rifle. If you’re interested in close quarter battles, then shotgun is your weapon. Pistol and revolver seem powerless in this case. Well, they still should be crucially important when you don’t have enough cash to buy others. You may think of that your avatar cannot shoot because of carrying a sword. Well, remember the title: Sidearm. The flying object next to you fires the weapon you’ve selected with your aiming commands. Immobilizing yourself will nothing to do but to make you a piece of cake for enemies.
