Did all the upgrades using the endless mose for a comparatively quick grind. I was incensed to discover that the light string minigun is actually better than any of the guns that come after, and I see no way to downgrade.
Good thing my turrets do most of the fighting for me.
You'd think that after putting bullets through their heads, hacking their heads off etc. would make you reasonably able to guess what would happen if you, say, apply a drill to their foreheads.
Hint: If you have all the regen and health regaining perks, use the active barrier. if you hold down the button and kill away, you become effectively invincible.
