GOW3 Co-op成就問題 - XBOX

My Fellow Gears (鐵哥兒們) 50G
Complete all Campaign Acts in Co-op
(any difficulty, Standard or Arcade).

We Few, We Happy Few... (我們幾個, 快樂的幾個人呀...) 50G
Complete all Campaign Acts in 4 player Co-op
(any difficulty, Standard or Arcade).

Welcome to Arcade Mode (歡迎參加過關挑戰賽模式) 10G
Complete 5 Arcade Campaign chapters in co-op
(any difficulty).

以上三個是合作戰役的成就,

由敍述看來是不是乾脆一開始就玩4人戰役,

然後選簡單 and Arcade Mode完成所有章節就可以一併解開上面三個成就?

也會解開其他所有故事戰役的成就. (除了困難 & 瘋狂全破)
