Trophy Type: Bronze.

For this trophy you must kill a total of 20 zombies in a single explosive kill. The title is a bit deceiving as you can use more than one explosive device for the kills it just needs to be at the one time. This trophy stacks with Somebody's got to survive! and My family's always been in meat.

This trophy can technically be obtained anywhere in which you can gather 20 zombies in one location. A good place to attempt this is at the beginning of the 'Library of Death' level from Episode 1. You will firstly need to set Enemy Spawn to 'For 4 Players' as this will increase the number of zombies in the level. Also, make sure you equip 2 x Dynamite and 2 x Grenade as your loadout. The following video by 360GameTV shows the exact location and method for obtaining the trophy:
