I died from the fly things (I don't know the name off the top of my head, sorry lol) that you kill with Codsworth. Thatâ��s not what makes this mod great, though. In terms of combat mods, this one is a must-have Fallout 4 survival mod. The Realistic World Map mod by Vastias takes Fallout 4’s muddled old vanilla map and replaces it with a much more detailed version, featuring roads, bodies of water, and land masses.
