Halo: Reach Credits (cR) Farming Legitimately in Single Player

Difficulty: Legendary = 2× base cR + commendation progress.
Skulls: Gruntpocalypse (Grunt Birthday Party + Mythic) = easy multikills.
Loadout: DMR + Plasma Pistol (noob combo) / Rocket Launcher / Sniper.
Matchmaking Firefight: Faster than Custom (auto-matchmaking bonus).

No exploits or "easy credit" glitches—they're patched or ban-worthy. Legitimate methods are efficient enough.
