Added in Playtest #9, Observation Posts are features of most Capture the Flag maps that allow for extra options for teams who choose to capture and defend them.
By default, Observation Posts are neutral and not owned by any team. A player can capture them by use of their Repair Tool, and after capturing them they provide several benefits to the team. The primary benefits is that while your team has control of an Observation Post, if the enemy flag carrier is in midair for 10 consecutive seconds, the Observation Post will call down a destructive orbital charge on the enemy flag carrier, making it significantly easier to return your flag. The enemy flag carrier can reset this 10 minute timer by touching or skiing on the ground.
While owned, there is a teleporter near each respawn point that can be used to teleport directly from the spawn to the Observation Post. Each Observation post is also defended by one or more turrets, which may be destroyed similarly to base turrets.
