Bu senenin en çok beklenen oyunlarından biri olan Mass Effect 3'ün X360 Achievement listesi xbox360achievements.org sitesinde ortaya çıktı. Toplamda 1000 puan olan listede, Kinect'e özel başarım puanı bulunmuyor. Galaxy at War'da oyunun büyük bir kısmını tamamlayıp, her görevi "Insanity" zorluğunda başararak ana hikayeyi bitirirseniz dolgun ödüllere sahip olacaksınız ki, böylece oyun sonunda Insanity'de 75 puan kazanacaksınız.
"Long Service Medal" için oyunu iki kere bitirmeniz lazım veya Mass Effect 2'deki kayıtlı oyununuzu Mass Effect 3'e transfer etmeniz gerekiyor. "Paramour" başarımı için de başka bir karakterle başarılı romantik ilişki yaşamanız gerekli. Önceki oyundaki bir ilişkiyi bu oyuna da taşıyabileceksiniz. Muhtemelen PlayStation 3 versiyonu için bu başarım listesi aynı olacak.
