This mission appears when you complete the main quest Dr Kessler. Talk again with the scientist, who'll ask you to look for any useful items in the tunnels.
Enter The Tunnels
You can start this mission when you get to the sixth chapter, when an access to The Tunnels is unlocked. Head for Santa Maria Mission and use an entrance next to the pump.
Find traces for Kessler
In The Tunnels you have to find three items. You find first trace just after using a ladder leading to the lower level of tunnels. Approach the green goop.
Take a sample of toxic chemicals
Carefully take chemical sample without touching the substance.
Find an anomaly
Second trace is just after the one above. Turn left, opposite to where the game shows you to go. Eliminate zombies and your way and get to the new spot of goop.
Take a sample of tissue
This time examine a body of mutant and take Tissue Sample.
The last trace is in the biggest location of The Tunnels.
Get onto the lower level and go left to get on the balcony with few fenced rooms.
Search the last room with few Walkers. The item you're looking for is notes lying on one of tables.
Talk with Kessler
Return to the BioSphere Laboratory when you can (use Fast Travel). Give all items from tunnels to dr Kessler to get a Golf Club.
Unlocked event: A New Machine (to unlock this you have to talk with Dr Kessler in BioSphere Laboratory).
