In this Stickmen game you're a sniper protecting a witness who does not know he is being shadowed. Kill all the assailants and eliminate all the threats to your witness without him ever noticing until he can testify. Here is a sniper game that requires some subtlety. Think up creative ways to protect the witness without giving yourself away. Hint: Sometimes it all comes down to timing.
Use the mouse to shoot and Z/X to zoom in and out.
