Has anyone been able to downpatch their steam version of the game from v2.0, been stuck trying to get it to 1.1 but with no luck.

Hey there, I got mine to work today.

Step 0. Put Steam in Offline Mode Step 1. go to the resources tab on the side. Step 2. Download the Borderlands 2 1.1 exe & the last file on the page titled "Updated Patcher" (Use This) From here, I used the instructions in this video and they completely worked for me.

I think that interface is suitable, Slice Master but i haven't thought of other changes.
