Project Chameleon is a stealth game where you must shape-shift into objects to go unnoticed by your enemies. Play as Siren, an elite spy executing missions around the globe. Manipulate your surroundings, set traps, and use powerful gadgets in each mission.

Siren is a spy who works for an agency focused on terrorism and conspiracies. She discovers that Viper, her mentor, is dead and that he left her his chameleon suit, a suit that is only given to the agency's highest-ranking agents. Siren is then chosen to be the new chameleon agent, replacing Viper. The chameleon suit is capable of simulating advanced holograms allowing the user to blend into the environment, becoming one with the scenery.
