自 2009 年 E3 電玩展首度亮相後，Rockstar North 所開發的《AGENT》至今已經歷過 PS3、PS4 時代還孵不出來，如今確認 Rockstar 已放棄這款遊戲的商標。
在美國商標專利局（United States Patent and Trademark Office，USPTO）關於《AGENT》的註冊商標網頁中，其狀態明確表示「因在發出通知後沒有及時提交使用聲明或延期申請而被遺棄」，顯示 Rockstar 已在 11 月 19 日確定放棄《AGENT》的商標名稱取消開發。
《AGENT》之前亮相時被描述為是一款潛行類動作遊戲，背景建立在冷戰時期，在 2009 年時被當成 PS3 獨佔作品公開。然而，這十年內《碧血狂殺》、《俠盜獵車手 5》以及《碧血狂殺 2》都出了，本作依然杳無音訊，如今確認其商標已被放棄，也算是給苦等的玩家一個交待了。
