Splinter Cell: Chaos Theory Hints

You need to do this in Co-Op. One person will go into hack or pick lock or use keycode screen.

While the other is looking at this, the other one will shoot him with a sticky shocker and they will fall on the floor.

While on the floor, you will take out your weapin and stand up.

You are now invisible and invincible and your old body will be laying on the floor.

Use sniper attachment and get two or more guys in your sights lined up and the 20mm round will take them both out.
