With a free Prologue available to try out right now, developer EggNut has announced that Backbone is pretty much content complete.
Quite exciting, as Backbone: Prologue which arrived on Linux officially back in October 2019 has been reviewed exceptionally well by users on Steam. That's really encouraging on what to expect from the full game when it releases next year. The developer said in the recent announcement that, amongst other things, "Backbone is almost done" and it sounds like they don't have much left to do apart from a big polishing pass on it.
Check out the new trailer below:
As for the final release, they're aiming for a Release Candidate build for Q1 2021 but that may see a delay due to them being less productive through the COVID19 pandemic. Fair enough really isn't it? I don't know anyone who has been full-steam ahead over the last 6 months and we've seen many other developers delay. So at somepoint next year, we will get it but it still sounds like it's been going quite well overall.
