In halo reach there is some small moderations. The Rifle is slighty more accurate and has a new visual upgrade. But the assault rifle in Halo 3 is much better becuase it has more ammo (the rifle in reach only has 32 and the rifle in halo 3 has 60) and is the original version.
Halo 2 has the gravity rifle in it but i (think) you have to have the custom edition to get the gravity rifle.....
Target locater, Sniper,Focus rifle,and energy sword
The 3 round burst gun from halo3.

ODST does'nt have the AR.
if you are refering to halo reach as halo 4 yes, yes their is... some examples: plasma repeater (its a more rapped versoin of the plasma rifle and has auto vent, focus rifle (its a laser basicly),gernade launcher , duel wealding is gone (not a weapon)and i thinks their might be more but i don't think so...
Yes you can. The easiest way to do it is to pick up the Focus Rifle in Forge, fire it and go into monitor mode.
