REX Engine 是 RE Engine 的下一代版本。官方表示，這款全新引擎具有「高性能」、「高穩定」和「高效率」三大特點，運用「RELauncher」和「REProfiler」等工具，將帶給玩家更高品質的遊戲體驗。
根據遊戲評論家 Okami Games 的說法，REX Engine 將包含 RE Engine 的所有功能，同時增加對新技術的支援。
REX Engine will include all previous features of RE Engine while adding support for new technologies and handling the growing size of assets more efficiently.
