The Drones showcase has a red circular "AO" = Area of Operations marker and trigger. If the player leaves this area, the mission ends instantly and unsuccessfully due to "Missing in Action".
Observed: The final objective exfil point is a rather inconspicuous building within 20m of the edge of this trigger. It's quite easy to accidentally leave area of operations.
Expected:
- Area of operations should be large enough to allow reasonable room for tactical freedom and minor errors in navigation.
- Missions should never feature fail without warning triggers! Give warning that player is leaving area of operations prior to ending mission.
