Psi-Ops: The Mindgate Conspiracy is a video game developed by Midway Games for the Xbox, PlayStation 2 and Microsoft Windows PC platforms. Originally titled ESPionage, the game was released in North America on June 14, 2004; the European release followed on October 1, 2004. A traditional shooter in many respects, Psi-Ops banks on its ragdoll physics (by way of Havok 2.0) and variety of psychic powers to differentiate itself.

In the game, the player is Nick Scryer, a "PSI-Operative" whose mind has been wiped so he can infiltrate a terrorist organization. However, he is captured and must fight his way out with the help of Sara, a double agent. As he progresses, he regains his PSI powers.
