The core gameplay is still the same, using stealth and shadows to eliminate or subdue targets, collect information and such. The controls have been slightly modified for the PSP, the analog being used for movement while the d-pad is used for the inventory screen, but the most notable feature is holding the "O" button will allow the player to pan around with the camera, while a single tap will reset the camera directly back to the third-person perspective. As before, gadgets such as night vision, thermal, as well as lockpicks and weapons from the previous games return as well as a new feature designed exclusively for the game, where players can challenge a human opponent via Ad-Hoc in an online spy vs. spy deathmatch.
