Touchdown!

Touchdown! is a trophy and achievement in Fallout 4.

Requirements
Score a touchdown.

The player needs to be killed by a nuclear explosion, namely the super mutant suicider's explosion, but can also be killed by a Fat Man in order to get this achievement.

Behind the Scenes
The name "Touchdown" refers to the suicide mutant's act of throwing the nuke on the ground like football players are known to do when celebrating a touchdown.

It is also a reference to the "Nuclear Football," a device created by the U.S. Army.
