Encounters are smaller scale missions found around the city. There are multiple encounters to be found of each type.
At the locations of each encounter check the area for highlighted containers with supplies to help upgrade the various wings in the Base of Operations.
Types of encounters are:
Medical These encounters involve clearing an area of enemies. You will then be asked to search the area for a key (highlighted on your hud) to collect and then proceed to release the hostages from a locked room / cell.
Security In these encounters game members will have occupied a building and you will be required to take them all out. They may be several waves of enemies.
Security You will encounter JTF agents under attack from gang members. Help them take out the waves of enemies that may come from various direction until the attack is over.
Medical Collect data on the virus by activating the highlighted research consoles. You will have a time limit to activate them all (2 or 3) which will be places in or around a building. Once they are all activated you will then need to proceed to a marked location to upload the data (also in a time limit). The upload location will be guarded by enemies that you will need to take out before completing the mission.
Tech Travel to the location of the arms deal and take out the enemies present. You will then need to tag the crate for JTF pickup which start the second wave. Here you will need to defend the crate against several waves of enemies who will try to destroy it or kill you. You must hold out for a set amount of time until JTF agents arrive to claim the crate.
Medical Enter a tunnel system to find a Water supply / pumping station. There will be Cleaners here attempting to sabotage the water supply to stop the JTF from putting out their fires. Clear the are of enemies and then activate the water supply wheel to start the next phase. You will no have a time limit to move to and activate several more water supply controls within the room but you will be under attack from more waves of enemies as you do so. Clear enemies as fast as you can and move to the control point. Once you have successfully activated all the controls and cleared all enemies the mission will end.
Tech Mercy drop encounters involve reaching a supply drop that has been captured by enemies. Clear the area of enemies and then defend the drop from further waves until the timer runs out and reinforcements arrive.
Tech When you approach the location there will be Rioters stealing supplies. Take out the enemies to clear the area first. There will be supply boxes on the ground that you need to pick up and carry back to a storage box. Picking them up will force you to move slowly and you will only be able to use the sidearm (pistol) to shoot. Waves of enemies will appear to try to stop you. You can drop the box you are carrying at any time by going into cover or switching Weapons. Make as much progress as you can between waves to move the boxes to the storage location. Once all boxes a stored the JTF will appear to collect it and control the area.
