Invisibility

Invisibility is where the player becomes hidden for a period of time. Each type of invisibility is different. Some only last for short periods of time, while others can last for around a minute. When a player is invisible, their cloak can break. This can be broken by spells, debuffs and breaking silence. Breaking silence is when a player uses a loud weapon while invisible, i.e. a rocket launcher, and their invisibility goes away. Each weapon breaks silence at different rates. A bow, dagger or silenced pistol are among the best choices of weapons to use when invisible because they are relatively silent.

Camoflauge-Hunter;
Camouflage is where a player blends in with the surrounding area and can not be seen. This type of invisibility lasts for the longest, but is one of the easiest to see if the player is moving.

Invisibility-Shadow;
Shadow classes all have the ability to turn invisible for a period of time. This can be useful to stalk their prey or to get to places while not being seen. This invisibility is the hardest to spot when moving and can be used to launch seek attacks on unassuming victims. When they kill an enemy however, they become visible for a split second.

Invisibility-Restricted Operatives;
Restricted Operatives have the ability to turn invisible for a short period of time. This ability is mainly used for hidden traversal of areas. The player has a distorted outline when running though.
