Yes, the scientists (those remaining at least) claim you can be brought back. Well, I mean, there's a chance you'll be back. Shouldn't take more than a week.
Alas, things would be easier if you had written about your past to help with understanding your neural structure.

Alternatively, there's a possibility of merely showing your brain activity by bumping up the research team. Scientific community (what's left of it) agrees however that it is worse option of the two

Warning:
A key was bought on GMG, and the store only shows me that "This product will activate in the region of purchase.". While it's good to know, it might mean some mean regional restrictions. I'm almost certain it can be redeemed in EU, and fairly certain it should be redeemable worldwide. Without 100% certainty, should problems arise, I ask that you'd let me delete the giveaway.
