Area9800 Landingzone is the fourth map in Tilarus-5, one of the campaigns introduced in Alien Swarm: Reactive Drop. It is very similar to Area 9800's Landing Zone map; however, while Area 9800's version requires a computer near the lowered bridge to be hacked (in addition to the panel hack required to raise the bridge), Tilarus-5's version lacks this objective.
