卡普空為《生化危機4：重制版》PC版推送新更新，卡普空現移除了此前加入的已移Enigma加密保護。
更新后，除生《生化危機4：重制版》的化危護Steam商店頁面信息中已不再顯示該游戲包含Enigma加密。此前，機重發行商因加入該加密措施而受到玩家批評。制版數毛社曾確認，新加Enigma加密確實對游戲性能產生了影響。密保此外，卡普空現該加密還干擾了游戲模組制作所必需的已移REFramework工具的正常運行。
值得注意的除生是，本次更新后游戲的化危護可執行文件（EXE）體積不降反升，較移除前增加了約140MB。機重盡管當前文件大小仍低于此前搭載Denuvo加密時的制版版本，但這一異常變化引發外界關注。新加有分析認為，卡普空可能用其他加密方案替代了Enigma，具體技術細節尚未得到官方證實。
