Look for an entrance to the workshop | Chapter 5 - Pump Action DI Riptide Guide
Last update: 11 May 2016
Main door to Jimmy's Workshop is closed, so you have to look another way in. Pick up lying here and there molotovs and turn right, heading for northern east (you'll run into another Drowner, which can be avoided easily). When you get to the corner balcony, turn left and jump to the water.
Find a ladder (screen above) which allows you to omit destroyed balcony. Now head for southern west.
Approach the new ladder, which takes you on a roof of building next to the workshop. Localize a narrow passage between roofs, heading southern west.
Stop where the screen above shows - the area is strong with Walkers. Use freshly found molotovs (or explosives) to eliminate them.
Jump to the fenced area and open side door of workshop. Inside, you find Walkers, a Thug and a Suicider. Defeat them, because when you pick up pump, you won't be moving fast.
