I did the pre-order survey on borderlands.com for a regular game then ended up upgrading to the same one as my family member and they have more free stuff under their profile. I was wondering if i would still get the same thing as them later on when i download them game?
Survey has nothing to do with your pre-order bonus asigned to specific version of the game.
I took the survey before I even pre-ordered the game.
The survey just counts towards the VIP rewards. As long as you have everything linked through SHIFT, you should get those rewards once you have the game installed, launched and signed in to SHIFT. The rewards attached specifically to the game pre-order should install with the game - got mine queued up at home right now.
