The Ecotologist Compound is an area in Postal III.
Eco Zealot HQ Assault Edit
After finding a map to the compound (and due to poor Yorick getting fucked to death), the Postal Dude managed to get himself a spot on the SWAT team before a raid on the compound. The mission is to take Al alive.
Meet the Zealots Edit
After helping the Ecotologists with their Robbery (or not), the Postal Dude gets taken to their compound to meet their leader Al. After a chat, thus begins the Super Fun Apple Picking mission.
