For Mechwarrior 5, I use the following mods in the following load order. This set is also used for Coop, both locally and online. As Mod Manager, use the MW5 Load Order Configurator 3.4 it allows sorting mods by their original Load Order Number (oLO). General advice is to only change the original Load Order, if you know why.
