Guide Splinter Cell

You play Sam Fisher, an elite, intelligence-gathering
operative who moves like a phantom and strikes like a
serpent. You work for Third Echelon, a secret government
organization that gives you all the support they can from a
remote team—and will disavow any knowledge of your
existence should you fall into enemy hands. You are a
Splinter Cell, a lone agent sent into fortified hostile
positions to accomplish what all other conventional means
have failed to do. Should you fail, the world grows that
much darker.

Unlike most military simulations, Splinter Cell Pandora
Tomorrow doesn’t rely on guns and ammo. Sure, you’ll break
out an occasional assault rifle or grenade to mop up the
competition when they get uppity, but more often than not
you’ll use your eyes, ears, and stealthy dexterity to slip past
enemy after enemy undetected. You don’t have the
armament to battle your way through a whole enemy
complex, so you’ll want to slip in unseen, grab the designated
intel, and then slip out just as quietly.
