Fallout 4 Easy TOUCHDOWN Location (Mini Nuke Method)
Fallout 4 Easy Touchdown Method 2
Another Method of getting a touchdown in Fallout 4 is to get nuked by an enemy. One of these can be found early on in the game. East of Vault 111 is Skylanes Flight 1981, a plainwreck next to the broken highway.
Starting from that position, head north underneath the highway and look for an antenna. It marks a small enemy base that has an enemy carrying a Fat Man (Mini Nuke Launcher).
All you have to do now is get killed by his Mini Nuke to earn the Touchdown Achievement / Trophy
