Quick question: do kills with the Halo 2 beam rifle and its different variants count as kills towards the beam rifle commendation?
I don’t think the Halo 2 Beam Rifle doesn’t count towards the Beam Rifle commendation, as it is coded as a separate weapon from the Halo 5 Beam Rifle.
I would suggest testing this. Check your Beam Rifle kills, then get one with the H2 Beam Rifle and see if it changes.
I do not believe so, but should be pretty easy to check.
