You will become a chameleon, an agent without a past who is able to stealthily infiltrate any place in the world. Searches for killers take you to various places locations - the poor Moldova, Afghanistan in the midst of dangerous wild fighting between the Soviets and the Mujahideen and to Lebanon, where the Israeli army carried a crack down on Arab terrorists.
The gameplay is mainly focused on stealth and fighting. To meet the challenges, you will be using spy equipment (a device for night vision, binoculars, minicam, jimmy or camera). Some of the necessary gadgets are picked up automatically before a mission, while some of them can be added according to the player's taste or game style.
Of course, there are weapons including pistols (i.e. Desert Eagle, Colt 1911), machine guns (i.e. MP5, AK-47, MiniUzi, Dragunov) and even mini-crossbows.
However, the player can choose an action approach in the mission if the proper gadgets are available. Enemies can be tough so using stealth is sometimes more viable than shooting. Paralyze or choke can be used to dispose of an enemy to surpass critical passages in the game.
The player decides what weapons to use and how depending on the situation. Sometimes a head shot is the faster solution, but it should be chosen very wisely or it may mean the big difference between life and death.
In short, Chameleon is more stealth than action game but in case you like a challenge, grab a gun and shoot them "all".
