Objective mode is one of the four game modes for Zombie Panic: Source. Objective mode differs from Survival Mode, as it requires the survivors to traverse through the map completing its objectives while defending themselves against the zombie horde. In this game mode the humans all spawn in close proximity of each other in one area before they venture off into the map. The zombie team initially consists of a single Carrier Zombie who must try to stop the survivors from advancing through the map by killing and infecting them.
Because there is no life limit for the zombies in objective mode, camping becomes a useless tactic and players may want to consider spending their ammo less, and conserve it for times of need.
