Nope.
The new tunnel-thing looks decent, but it took waaaaay to long for them to fix the issues with loot n stuff for me to come back now.
I liked the game, got my moneys worth certainly and I even liked the story somewhat. All the glitches, bugs, loot exploits and shit that was never fixed, however, destroyed any chance I had to enjoy the game about 4 weeks in and neither me or the people I regularly play with has any desire to return. Its a pitty, because I think the game could have been great, but they were obviously not experienced enough with how these sort of games work and just to what lenghts the people playing them will go to when it comes to exploiting stuff.
If you could play this like Borderlands with a 4 person group with no other idiots running about, I think it would have lasted longer.
