Q: How often do you plan to update this mod?

A: It depends on how creative my head is feeling and whether I come up with new ideas, as well as whether there's anything left to fix or tweak. I'm working on this mod in my free time, and sometimes life gets in the way.
That said, there's a line in the "Information" tab which will keep the mod status. As long as the line at the beginning says something about development, I haven't abandoned the mod.

Q: Why can't I download certain versions?

A: Version 1.0.0 was never public, as it's the origin/fork of the mod made by Klonan, kubiixx, MrJakobLaich and Maoman.
Otherwise I will leave one or two older versions available for the players to switch between in case things wouldn't work out well on your end with the newest version available.

Q: Which version should I play?

A: The one with the highest number is generally recommended.

Q: The Companion I spawn with starts with Mk.2 technology?

A: That is intended. It's meant to serve as a "gift" to your beginning. If you lose that companion, then it's gone forever, and you'll have to wait until you research Mk.2 tier by yourself.

Q: How does progression with Companions work?

A: It's very simple: You research better tiers of Companion equipment as you progress through the game. Mk.1 to 4 are all researched on Nauvis, so you can reach Mk.4 before going into space.

Q: How can I increase the number of Companions that follow me?

A: By researching the vanilla repeatable technology "Follower robot count". There should be an icon "as effect" of adding +1 companion to your follower cap.
At the start of the game, you start with a maximum of 3 companion followers.
