Dead Island: Riptide - Definitive Edition

It’s better to use a sonic mine, you can blow up 10 corpses and they’ll give you a trophy

The description of the trophy is incorrect! You need not to kill, but to cripple 10 zombies (works on already killed zombies) by tearing off the limbs of 10 zombies with one grenade/mine. There is a place in the game where, according to the plot, we play music in the town hall building. I did this: after I put on the music, crowds of zombies begin to run in, opposite the stage there is a fenced-off rectangular fountain where zombies do not enter. From the inside, with a kick you remove 10 zombies in one place, you can use firearms, the main thing is that the corpses have intact arms and legs (hit the body). Then you throw a mine into this pile, and the next wave of rushing zombies explodes on it.
