Dead Island Side Quests Walkthrough - Crash
You get this quest from Laurie River who is standing on the side of the road outside the tunnel
You will usually run into Laurie while heading to second gas station looking for juice packs, doing the main quest Seek'N'Loot
Laurie will wave for help and stop you and ask that you help her husband get out of the car. They lost control of the car and it crashed on the side of the road and she wants you to rescue him
Follow Laurie down the hill and locate the turned over car. Try to get the door open. The door wont budge, and some zombies will come attack you. Kill them, then try the door again. This time it will budge. After Laurie's husband gets out of the car there might be some more zombies. Protect the Weavers.
After you've killed the attacking zombies, Laurie will thank you and give you the key to the trunk. Open the trunk and get whatever loot you find there.
This completes the quest and awards you 400 experience points.
