 Upon death, the infected player must wait up to 10–25 seconds before re-entering spawn mode, depending on how many players are on the infected team.When a tank is spawned in the game, infected players receive a message indicating which player will control it.The human-controlled infected can see their teammates' outlines through walls similar to the survivors, but can also see each survivor's outline, which is colored according to the survivor's health and fades out if the survivor refrains from attacking, running and vocalizing.
