Reduce chance of being seen:
When guards and cameras are in your way, take your time and do not rush. Taking
your time and thinking of all the ways of bypassing them is the best way of getting past the guard or camera.
Prevent reinforcements:
If you have been found, equip a small weapon and shoot their codec so no reinforcements can
be called.
Enemies run away:
If you have been spotted, also try taking out your biggest gun. At times, your enemies may get
scared and run.
Defeating enemies:
When faced with a single enemy, quickly go for his/or her radio or arm.
Using pipes:
When you see a guard next to a pipe ( which may be hot) shoot where you want the steam to hit your enemy.
If the steam hits his leg, he will start to limp. If the steam hits his arm, he will be unable to use his gun or weapon. If
the steam hits his radio he will be unable to call for back up.
