Fallout 4 NPC battles get a bit fishy with a 10,000 strong Mirelurk army.

Of all Fallout 4's animal enemies, the Mirelurk is probably responsible for the most deaths. Sure, Deathclaws are deadlier, but Mirelurk are everywhere - and often in numbers. One Mirelurk? No problem. Three Mirelurks, including a Legendary and a King? More of an issue. All of the above, plus a queen, and you were ambushed...? Nasty.

In his latest NPC battle video, Cosmic Contrarian envision an invading army made up of 10,000 Mirelurks of various ranks. Standing against them are just 500 Brotherhood of Steel units - but as we've seen before, there's very little that can put down a good squad of Brotherhood troops. Maybe it's a fair fight.

The battle progresses in waves, starting with an easily defeated wave of standard 'lurks, before progressing to - well, you'll see.
