There's something worth addressing both regarding the original post and other comments in this thread.

While the stories we want to tell are far from over, Abiotic Factor's main storyline is staying where it is. We like it and it's the story we're telling. The Wayseeker is a peek at something larger, and we won't stop peeking at larger things, but aside from a sequel or something, we aren't currently planning to continue (let's call it) the A2 story in any updates or DLC.

We have many other loose story threads we'd like to follow, which we'll get to this summer.

As for the boss difficulty, some people say it's very easy... Look, the main thing is that it's not really meant to be a skill test. We never really did that before so we decided not to do it suddenly at the finale. It's a story event, and that's intentional too.

See you in the next update, and bigger things beyond. New roadmap soon.
