Find another entrance to the staircase | Chapter 11 - The Crash DI Riptide Guide
Last update: 11 May 2016
Turn right and resume exploration of basements. Eliminate all zombies on your way, using explosive barrels. Soon, you'll get to the door with Walker on its handle. Kill him and open door.
Defeat more undeads and use a workshop if you have to. Open door and attack more zombies, moving forward. Soon, you get to a corridor with few side rooms. Search them, because they contain more or less useful items.
Be careful, because as you get to the corridor, you'll meet Walkers, Infested and a single Thug. As this place is very narrow, you have to eliminate him - I recommend to throw a gas bottle at him and finish him with firearm. After a while you get to a area on the other side of previously met closed gate.
