Hunter-Seeker
Find and kill all named champion monsters located in dead zones
There are a total of 13 champion monsters in Dead Island Riptide. They are all hidden in small side areas, the “dead zones”. The first six can be found in the Flooded Jungle and the remaining seven in Henderson. The entrances to these side areas are marked on the world map. After entering a dead zone you will get a side quest to kill the champion. The champion is marked on the radar with a purple skull symbol. The champions are stronger versions of standard monster types. Make sure you have some good weapons in your inventory and use your special skills to kill them quickly. They give lots of XP and also drop some nice weapons.

Twins
Kill the Twins
Location: Pinai Ferry Station
You will reach this location about halfway through the game while following the main story quests. You can also fast travel to this location later on. To unlock the trophy / achievement you need to kill two special gas zombies. The first one is located at the beach in the northern part of the map. He is easy to see and will attack on sight. The second one is a little harder to find. He is located in the southern part of the map and you need to climb a hidden ladder to make him appear. The ladder is behind a sign that says “Workshop”. The gas zombie is trapped in the workshop garage and will only come out after you have climbed the ladder.

The Hurt Mine Locker
Kill 10 monsters with one mine
A great place to get explosive mines is on the rooftop of the “Old Town Cinema” in Henderson. They will keep respawning in chapter 13, so you can farm as many as you want.

Once you have an explosive mine, go to the Ferry Station. Gather up a group of 10 zombies and jump on a car so they cannot hit you. Just shoot around to get their attention. Wait until 10 zombies are in one spot and start killing them. You may not dismember them with bladed weapons! Use guns or blunt weapons, their bodies have to stay intact. Leave one zombie alive and let it trigger the mine. The explosion has to destroy 10 bodies, no matter if these bodies are alive or dead. Of course you can also plant the mine while the ten zombies are still moving, but the blast might not destroy all bodies. It’s safer to kill them first.
