Hey guys, i got the game on Steam but i would like to support the devs on GOG too. Is the game up-to-date on GOG or is it behind Steam ? Thanks !

I don't know if there've been any recent updates that GOG is missing (the Liver update is the most recent one here), but in the past, it's usually been updated here at the same time or not too far behind Steam, AFAIK -- maybe a week or two later on a couple occasions.

The NERVE update ?

Yes. It was outdated here for some months before the update that Flesh420 posted about, but as of last fall, it was at parity once more. I don't know if there've been updates since that we haven't yet gotten, however.

Hello. If you are still interested in the situation with updates that are implemented to the GOG version of the game, you can read my post (This one). There I described what I found about all available updates for both Steam and GOG versions of Death Road to Canada. Thanks to services like SteamDB and GOGDB it is more easy to follow up the changes for the games.
