Defeat the drug dealers, tag the boats and increase your Good Karma.
Mission 11: Trash the Stash
At this point players have blue and red stars on their maps. One is for Good Karma and one for Evil Karma. We're keeping it Good and focusing on blue for this playthrough.
Go over to the docks and start taking down the drug dealers. on the map you'll see a number of magnifying glasses - these represent all the boats that need to be searched.
Fighting the dealers can become overwhelming, so be sure to back off and heal when necessary and use cover and the environment to your advantage. Aim for the legs for that extra Good Karma.
Once you've beaten down a fair few punks, Fetch will tell you she's found boats stacked with drugs. Head to each boat (see that magnifying glasses have changed to stars on the map) and you'll find a cooler at the back of each one with drug stashes.
Two of the boats are occupied so make sure you free them before going around to the front of the boat and tagging it for Fetch to destroy. Once all three are tagged get back to Fetch and fight off the horde of druggies - make use of Neon Beam. Keep checking the map as you may find more Blast Shards here to upgrade Delsin's Neon Powers.
Once you've met with Fetch you'll need to follow the drug truck - use the rooftops and when it stops drop down and take down the remaining dealers. Open the back doors to complete the mission.
