Destroy or turn off sirens | Chapter 9 - Militarized Zone DI Riptide Guide
Last update: 11 May 2016
Enter the Military Base and localizations of four sirens will appear on your minimap. First one is close to the entrance, on the north. Don't hurry to get there, because there is a mine field next to it. Use throw weapons to destroy mines. Alternately, you can use firearm.
I don't recommend destroying all mines, because soon new zombies will show up here. Especially, that there'll be a second Wrestler among them. Wait until it walks onto mines or eliminate it at once, using explosives.
When you get to the first siren you can play it in two ways: destroy it from the distance (1st screen above) or turn it off (2nd screen above, hold Action key). The first option is better, because otherwise new zombies will keep showing up.
When it's done, head west, beware of Infested and new mines. After a while turn southern-west to get to the area with set up tents.
Defeat nearby Infested and look out for few new mines. Find a second siren quickly. Here you can also choose between destroying and turning it off.
Search carefully this part of Military Base and then return next to the first tower with siren and find a narrow passage leading north (screen above).
Third tower is in the northern side of Military Base. But don't rush it, as there are few mine fields nearby. Wait until Infested run into them. Destroy or turn off the third siren.
The last siren is on north from this place. You can get there easily by going through the fenced area with few tents (screen above) as there are no mines. Instead, be ready to defeat the last one Wrestler using your own explosives.
Find the tower with last one siren and destroy it or turn it off. Wait for new objectives while eliminating running Infested.
