Trophy Description:Force an enemy to drop dynamite that kills two people when exploding.
Bronze Trophy.
This trophy is missable.

There will be a cutscene with Grim when you reach the second half of Shantytown and enemies will start throwing dynamite at you from that point on.

That is a good place to try and go for this trophy. Enemies will be relatively close to each other. Simply wait for an enemy to light the fuse of his dynamite and shoot him, but try not to kill him, so his dynamite can kill both him and another guy.

You can also create a custom save when you reach Shantytown using one of the other save slots, in case you miss your chance and finish the story. Thanks to F8L Fool for the tip.
