New Revolution DLC

It carries over. It takes forever to do. If you are playing as a Siren or a Soldier have a Double Anarchy with a ammo regen mod and go and kill the Clap-Traps that come out of the MINAC at the end. Just get up close when the door opens and shoot them. It will probably take 2-4 hours to do so but was much faster then the 20 hours of finding Clap-Traps in the other area's and killing them and waiting for respawns.

Shoot out all but one of MINAC's "eyes"...I left the front one...and that'll help keep you from getting shot at so much.

yes it does take forever about as long to do all the Underdome Achievements take to get but at least you'll get XP and stuff for killing all the spawning divine winds.

These achievements are just awful.  Anyone with half a brain should be able to see that.  I can't imagine why anyone thought they were a good idea.  I've got all the bobbleheads and the 3D glasses so far.  I've been running to the area where you're introduced to the superbad hyperion soldier or whatever he is, killing all the clap traps that spawn, exiting the game, and then reloading it so they'll spawn again.  I only need oil cans and pizza slices now...

Yep, you're right Adre...they are awful.  It took me 2+ hrs. a day for 3-4 days to get all of the collectibles.

They do not Carrie over it works just like any other mission, if you are doing a gun collector mission in PT1 you cannot go to PT2 to finish it. You will have to remain in search for the rest in PT1 if you think thats were you found the most.

Now we have two different answers.  One from Teddymouse and one from Sparks.  Looks like we need a ruling...Which one is correct?

While I have no definitive answer, my guess and vote goes to Sparks. Until someone proves otherwise, P1 and P2 have never carried over anything pre-robolution, so why should it now?

Umm...obviously you wouldn't expect anything mission related to carry over.  Other than that, what might you be referring to?  There's nothing comparable to these collectibles that also don't carry over in my opinion, so based on this answer, I am not inclined to believe you, troll.  

Edit:  This is a response to Silver Troll.  I thought I was quoting him, but the new forums SUCK, and apparently I was only "quick replying" or something.

Like I said, it's only a guess, and no one has given proof of either argument.

But I wonder if anyone might know, before the 1.41 patch you had to get all items for those achievements in 1 sitting, but was that changed in the patch, and can now, for example, collect 5 oil cans in 1 game, then 5 more in a separate game later, etc, til you get that achievement, or is it still 1 sitting?
