In my opinion the best guns are the brute shot, sniper rifle, shotgun, and the plasma pistol. But most people would normally take a battle rifle and shotgun.
A plasma pistol???????????????????????????????????? NO WAY!!!!!!!!!!!!!!!!!!!!
I would personally use a shotgun for close range combat and a SMG for mid range combat.
The plasma pistol isn't as bad as you'd think, but i think the first guy meant to say plasma rifle
the fuel rod gun, but unfortunately, there are very few of them in campaign mode, it is not on any multiplayer maps, and can only be forged onto a few maps
its not a gun but the energy sword
the best gun in halo would have to be the pistol if your playing halo 1, but if its halo 2 i don't know much about it but in the third it would definitively be the shotgun or assault rifle
no
i dont belive that you can in halo 3 i think it was exclusive only to halo 2.
no
Plasma Pistol, as it is in about all Halo games.
There is no "best gun", even tough the shotgun does have a one shot kill ability.
The 3 round burst gun from halo3.
You can't only on halo 2 and 3 you can
halo 3 odst
There is no best in Halo 3. There can be a team that is the best, but know single person is the "best".
Magnum
