Bad news from the Steam page : all upgrades have now disappeared !
It's disappointing not to be clearly informed of the different possibilities along time...
At the end I feel a bit frustrated..
It's 8 am in western Europe, 0 am PDT, no change on steam, you're surely right.
Anyway the most important is that we get the game on time and we will (preload just ended) !
A very good question since I still don't understand what will be my rewards (35$ post kickstarter pledge displaying "game only" contrary to a last post in this forum saying it corresponds to Hero Edition + collector's book and soundtrack...).
At this point, I'm totally lost with the rewards and hope I can upgrade tomorrow if no other products line appear on the backer portal !
