Intruded is a 3D exploration game about guiding a character from one end of a room to another, using only the WASD keys for moving and turning around. Your view of the protagonist is restricted to what you can see from a set of security cameras placed around the level, similar to the fixed camera angles used in early Resident Evil and Silent Hill games.

Certain rooms may have anything between one to three red orbs to be found. Orbs will only count towards your total if you bring them to the exit of each area safely, and a special bonus mode is unlocked if you beat the game itself.

Intruded is available to play over at Newgrounds.
