Clean the missions ruins | Chapter 5 - House of God DI Riptide Guide
Last update: 11 May 2016
Head for the main part of ruins and start zombie extermination. Look for supplies in this area (like med-kits and mines) because they'll reappear.
Besides Walkers, you'll probably meet a Drowner and a Thug. To eliminate them, use firearm or explosives. Eventually, you can use molotovs.
Your objective is to eliminate all zombies marked with skull. Localize now entrance to the underground (screen above). Listen to talk with Sam Hardy and wait until rest of survivors get there. The mission ends.
Main quest unlocked: Pump action (quest is automatically unlocked after finishing the described mission).
