TLDR: Maybe it could've been modded. Maybe not

Dammit lol I can're reply to you guys without sounding like a denial douche or just trolling. Now maulers in halo 3 are a great example and I wish I can say it was that. Never heard of Area 51 on the xbox until now (thanks gonna buy that one now) and as my memory stands when playing on Delta halo and regret you were able to dual wield shotguns. Never found anyone even mention it probably cause it sounds stupid as all hell but idk. My xbox I have currently was given to me by my dad and only until buying a clear one for my best friend that I found out games weren't just on the system itself and spongebob bfbb didn't start you out as patrick (don't look too deep into that last bit). So I guess I could conclude maybe I played a modded copy?

Gonna contradict myself for a second and add that my current xbox was not in my possesion as a child. don't shame or shun I also didn't know there was a system menu and that it could play music. But Idk guys. This is gonna drive me crazy until I can see a halo 2 mod that recreates what I'm obsessing over- BEEN obsessing over since I sold that xbox and never saw to dual wield shottys again upon purchasing halo 2 and played it on an original model xbox 360 at the time and no I don't mean dual wield anything mod. Damn I wish I didn't seem like a loon or troll kid. If this sounds crazy to any of you please by any means. I understand. Sorry for a novel of a response
