{{l4d series point|info_survivor_position}} It defines a point where specific survivors can be moved to and locked/unlocked in place by the [[info_director]] through the info_directors input/outputs. It is useful for creating introduction sequences that make use of cameras, as it allows you to guarantee where a survivor will not only be standing, but also allows you to use [[point_viewcontrol_survivor]] so that it can zoom in on a particular suvivors head, regardless of the difference in height for each survivor. This is important for creating professional looking introduction sequences for the first map of your campaign.

info_survivor_position is a point entity available in Left 4 Dead seriesLeft 4 Dead series Left 4 Dead series. It defines a point where specific survivors can be moved to and locked/unlocked in place by the info_director through the info_directors input/outputs.

This is important for creating professional looking cutscenes. Such as map intro and outro sequences.
