Sticky Camera Uses
Once you acquire the SC-20, you can fire sticky cameras. What you may not know is that you can fire them at the heads of enemies and knock them out without using your other weapons.
You can also pick up the sticky camera after you fire it (provided you can get to it) so you technically have an "infinite" number of chances to stun guards and other people.
If your camera is fire into a spot that you can't get to, you can try firing on it to "bounce" it somewhere where you can retrieve it.

Hint: Training Stage Secret
In the Training Stage, after you complete the task of looking at the lights, you can go over to the left or right of where you are. You will be above the lights, and you will find two doors. On the right is a door that leads to a room where a lock pick is sitting on the shelf beside the door. You can use this to get into the door that is located just beside the door leading to the covert-ops section. After going through this door and getting the keypad code (the code is 5656), you can then go on the left and get into the doorway to the left of the starting point of the level. Past this door is two rooms. In the last room is Anna Gromsdottir. You can talk to her about different things, but DON'T hit her or else you will be fired!
