Deathmatch

Deathmatch is a side quest in the Fallout 4 Creation Club content "Quake Thunderbolt."

Walkthrough
Upon arriving at the Cambridge Crater, three enemies marked 'Champion' will teleport into the crater; a super mutant, and two raiders. Depending on the player's level this can either be really easy or really difficult, in part due to the super mutant being armed with a missile launcher. One of the raiders will be armed with a double-barrel shotgun, while the other is armed with the Thunderbolt itself. The player's goal is to simply kill all three Champions, then loot the Thunderbolt from the Champion that was using it. Keep in mind that unless the player lures the Champions out of the crater, they will be at the mercy of the radiation, so it's wise to bring along Rad-X and RadAway for this quest. The Champions themselves also fight each other, so it may be wise for lower-level players to spawn them in, move to a safe distance and let them duke it out, then kill the last remaining Champion afterward.
