Gates of Hell
Collect Samples

Once again, progress normally and Dr. Kiesel will contact you for this side quest.

Hard to miss, it’s just before the Grenade Launcher attachment.

Before the big arena with a bunch of Processed and Scrapjacks, to the right, there is a blockade with an NPC. Interact with him to activate the quest.

Worm’s Armageddon

The second sidequest is after the bridge fight. Again, hard to miss.
Reward: Psychotropic Grenade x3
A Breakfast in France
A Fun Guy

This one is actually easy to miss because all the previous ones were kind of obvious. When you get the bike, there are some small ruins to the side and an audio log. Listen to the log to activate the side quest.
Reward: Rage Serum x3
Southern Belle Tower

After getting the bike and driving down the main road, you’ll come across an abandoned house. From the house, you will see a tower in the distance. You should get a call from Anabelle while driving towards the main objective, but if you don’t, simply head to the tower (shown in the screenshot) and you’ll get the side quest.

Droning On

This one is also easy to miss; After the combine harvester segment, before the exit, you can see a radio tower off in the distance. Go there to activate the side quest
Reward: Hacked Drone x4

Armed, Farmed, and Alarmed

After the mech segment, you’ll come across these large containers and a small white shack to the right. Read the note inside the shack to activate the side quest

After getting the quad bike, keep driving towards the main objective and you’ll get a distress call. If you don’t get it, simply drive towards the large smoke trail in the distance.

Vive la Resistance
The Art of War

Progress normally through the canal with Michelle and Sayid until you reach this split and take a right, under the bridge

Reward: Sadly, not a resors, just a Holodecoy
In Carcassone
The Princess and The Pie

This side quest even has a cutscene, you cannot possibly miss it
Reward: Master Key (unlocks some rooms with extra ammo)
