Basically finished Borderlands 1 Enhanced now, after the main game I did all the Zombie DLC (didn't need to), then claptrap DLC, I had to do the collect part achievement, but 3 of the grind for random things I left off. Last night I finished the regular General Knoxx missions and the easter egg stuff.
I then imported my original characters to give me certain achievements that could qualfy that i didn't want to redo (claptrap grinds and ALL the coliseum stuff), hitting levels 50,51,61 and finishing all DLC3 missions. Although the only one I was missing was Crawmerax.
So just 4 achievements left, 3 are coop and crawmerax. Will see if I can do it with my level 69 brick

I don't think I'll be heading to the pre sequel next, maybe some other games for a bit.
