These scientist are hostile if you get to close. They can be found patrolling junk piles, aboard the Cargo Ship, and protecting certain monuments like Military Tunnels and Oil Rigs.
These Green Scientist are not their blue brothers. These guys are only found inside the Outpost monument and will only attack you if you are deemed hostile (pulling out a weapon within outpost).
These BIG dudes are the toughest of the scientist. They are only found on the Oil Rigs once you trigger the timed crate on top.
These turrets are only found in Outpost and will attack anyone hostile.
Bradley patrols the Launch Site monument and is extremely aggressive.
The attack helicopter will periodically fly into the map. It's highly aggressive towards players that are wearing more than 2 articles of clothing or have any ranged weapons (except the bow) in their hot bar.
Chinook will periodically fly into the map. It will also fly into Oil Rig to drop off Heavy Scientist once the crate timer in started on that monument.
