How do you snipe on halo 2?

click on r3 once for 5x zoom and click it again for 10x zoom then press r well, first get a human sniper, clik in the right thumb stick once for 5x zoom, then again for 10x zoom. Now aim at sumone's head and fire...if you wanna get good, instead of being a nOOb and playing on easy, play on legendary. You get good fast. Also get used to using sensitivity setting 7. Once you can jump off of the top of Red base on Coagulation and headshot 2 ppl from halfway across the map b4 hitting the ground, then you can call urself good. (Note: to do that you have to learn how to snipe without zooming, requires good eyesight, god coordination and practice, it can be done!!!)
