Go to the Dead Zone | Chapter 3 - Where the Dead Live DI Riptide Guide

Dead Zone is in the southern part of Halai Village. Go there. On your way avoid mainly Thugs, Suiciders and Drowners if you don't have sufficient weapons for them.

The other thing you should know, are places in the village, where new Infested jump down from the roofs. Try to get out from such locations very fast, because sooner or later a new group emerge. Building to which you have to get is shown on the screen above.
