This tip could save your life. When you are completely out of harms way, shoot a transporter pod somewhere onto the ground. When you are about to be killed by someone or about to fall off the edge of an arena, simply change back to that gun and transport back to safety. NOTE: the pods will dissappear after a somewhat long while, so you might want to shoot a different one every now and then, but don't worry the ammo for it recharges. Also, if you are falling off an edge and you haven't set one yet, quickly shoot one onto a "ground" and teleport there, or shoot it into the air and repeatedly teleport up.
