In that case, I withdraw my statement about Fallout 2's bug fire. It's totally possible that I misremember after all. But FTBOS was finished (again) just months ago so I can vouch for its state. Redux is a mod, ie the game was changed according to modder's vision. It depends on whether you like that vision, is all.
If you dont like Redux, it's possible that you will like Equilibrium. This guy doesnt like much of Endocore's Redux's vision, so he based his mod on Redux, but change back a few things. Again, it also depend on whether you like his changes. They are both mods, not patches.
As for Supermutants with M2, the method is using the APC to reduce damage, AND sniper duel at extreme range, ie they can not shoot back (so that we can have some ammo as loot). If they move into range, have the APC backtracked. This method is slightly economical regarding DU ammo.
OR. you can have some specialist with BG, drugged to the eyebrows, sneak to their backs and burst fire first. This method is risky and DU ammo dependant.
