I bought Shadow Warrior 2 like a week ago or something and now it's for free. Can I get my money back?

Contact support regarding a refund and see what the response is. My guess would be "no" unless you have issues running it on your system or something similar to that problem, but you might be surprised.

The downside of all this is - in the time it likely takes GOG support to respond, the giveaway period will have been over. In the event they do grant a refund, you'd essentially be without the game twice, but at least you'd have your money.

Maybe you will get compensation in other ways. Good luck to you.

If you ask them kindly you can prolly get a refund or atleast the money back as store credit.

Thanks, everyone. I probably will contact support for this. Maybe I'm lucky

I bought SW2 8 days ago, too, and feel ripped off. The fact that the game was already discounted back then doesn't really help. (The discount caused even more existing customers, including me, to pay for the game.)

For the discount, remember that it was not certain that Shadow Warrior 2 would be given away for free.
