Bungie har sendt os nedenstående billede, som indeholder alle 49 achievements som findes i det kommende Halo: Reach. Præcus hvad hvert ikon dækker over, vil udvikleren dog ikke afsløre, og i stedet er det kun blevet til seks beskrivelser - lad derfor spekulationerne gå i gang.
• A Monument to All Your Sins - Complete each Campaign Mission on Legendary - alone.
• Banshees, Fast and Low - Hijack a Banshee during the Reach Campaign.
• Yes, Sensei - Earn a First Strike Medal in a Matchmaking game.
• A New Challenger - Complete all of the Daily Challenges in a given day.
• Make It Rain - Purchase an item from the Armory that requires the rank of Lt. Colonel.
• If They Came to Hear Me Beg - Perform an Assassination against an Elite to survive a fall that would've been fatal.
