Any idea when this will be on GOG?

It's already on Steam with a 40% discount if you own Talos 1 & 2.

I am interested, too.

GOG anyone reading this and care to give a statement on this?

I bought it on Steam but will buy it here!

BUT, it's crashing like crazy on my system after 15-20 minutes, not sure if it's my 13th Gen intel CPU that's the cause as no other game crashes!

I've emailed Croteam a few days ago about the crashes but no reply yet!

Seem to have solved the crashes!

I have 2 AIO fans that were intakes and forcing hot air in the case to re-circulate, so I bought 2 sets of Noctua AF140x25 G2 PWN fans and sandwiched the radiator between them so the bottom fans push air through the radiator and top fans exhaust out the top of the case so both fans are now exhaust fans and the temps went down!

Also changed the side 230mm fan for a Noctua NF-A20 200mm PWN fan that runs faster than the 230mm fan and shifts more air, this is an exhaust fan, similarly the 140mm rear exhaust fan I changed for a Noctua NF-A14 Industrial as it can go up to 3000 RPM, but i've set it 1200 RPM and you can only just hear it!!

Also regreased the CPU with some Kryonaut as that's a lot better than the MX-5 I was using and also adjusted the radiator fan curves so they are a constant barely audible speed and only ramp up when the CPU hits 70°C and so far they haven't ramped up yet as I can play Talos Reawakened for more than 1 hour now and no crashes!!
