This is another thread of three quests, starting with a distress call from Hana to rescue your Halperin Hotel pal, Rav. This starts off the ‘The Rav-Ages of Caustic X’ quest, which has you kicking zombies into a pool of caustic goop at the Halperin Hotel. The second quest is ‘Boz Makes a Bang’, where you’ll receive another call over the radio (we found it after initiating the ‘Blood Drive’ story quest, in the Serling Hotel lobby).

The quest has you helping Bozzy by deploying mortars on a WWII movie set at Monarch Studios, to fend off hordes of undead. Finally, the third and final quest in this thread is ‘Dez and the Mother of Satan’, a mission that takes you to the CDC Center at The Pier. You’ll find this via Hana over a radio receiver once again.

Complete this last quest by helping Dez, and the achievement will pop. You'll also get Dead Island 2's mystery goodie box code too, and be able to get your hands on one of Dead Island 2's best weapons.
