Guards
Guards have three different alertness levels. Curious guards will try to check on something going on. Suspicious guards are those that find a dead body. Alarmed guards are created by shooting a target in front of them or when you hit them with a non-lethal body shot. When the radio icon appears above their heads, you only have a few seconds to eliminate them out before they call for help.
Kills
Always avoid killing targets in plain sight. Guards will alert other people and your target will move to safety. The only time it is usually safe to kill in the open is usually during the extraction process, when there will not be enough time for witnesses to sound the alarm. Look for ways to dispose of bodies. Consider using water and the sides of buildings when available.
Rifles
New rifles can be unlocked by naturally advancing through the game, reaching a certain position on the leaderboards, or by collecting the required number of parts. Specific weapon parts will corresponding to various targets.
