This feature takes note of how the player plays and shows it to the other players through the color of the player's blip. Performing aggressive actions, such as killing other players or harming pedestrians, will cause the blip to transition from white to red. Certain actions will make the player blip redder depending on what the player is doing: for example, killing another player will redden the blip faster than if the player blows up a car or shoots down a pedestrian. Killing a player with a white blip increases the player's mental state more than if the player kills a player with a red blip, however killing a full-red player will not increase the player's mental state. The player receives more RP for killing players with redder blips.
The Mental State has 5 levels/bars just like skills with their own designation as listed below:
0-19%: Normal (White player blip)
20-39%: Unstable (Light pink player blip)
40-59%: Deranged (Pink player blip)
60-79%: Maniac (Red player blip)
80-100%: Psychopath (Blood-red player blip)
Doing a series of jobs will lower the player's Mental State, which may be reset to 0 if it falls into the Normal range.
