Kill all attacking monsters | Chapter 1 - Back to Reality DI Riptide Guide

When the Horde attacks, return to the bridge on the west, because it's the only one uncovered path leading to the camp. Eliminate zombies here, beware of the more agile ones and don't get surrounded.

In the further part of battle, head for the central part of camp, because remaining zombies for sure got into. As previously, focus on saving allies. In the meantime, you can repair fences, especially as some zombies will join the battle later. Fight until the bar of Horde goes down.
