Wait... what 'loopholes' did you get with your Eilte account? Iv looked all over but my extra $50 didnt allow me to do anything different.. other than wait for a week past NORMAL XBoxers (not premium) to get my premium content, but I dont call that a perk.
Report the player. He is using a glitch through Elite to get two attachments on his/her gun. I ran into this before, guy was using FMG-9 Akimbo w/ Ext. Mags and Damage. It is an exploit through the Elite website that should ALWAYS be reported, as for any exploit.
no desert eagles can not have 2 attachments and it does not have suppressor and yes like kylet said they did a glitch i have ran in to a guy using mp9 akimbos silenced *SIGH* man the world cant play without cheating at a game
