Can I save my progress?

Sadly, there is no save support for multiplayer games. What Remains is meant to be played in a single session of 2-4 hours. If you are playing singleplayer through the Scenarios menu, you can indeed save.

Can you add the ability to save?

No, this is not in the plans. The development work required to support saving/loading is prohibitively time-consuming.

Will you add more maps?

Possibly. If there is enough interest, and if time allows (this is a hobby, afterall), we may add support for the other official maps: Stratis, Tanoa, Malden, and Livonia.

Will this work with my 152 favorite mods?

I'm not sure! The config changes added by the What Remains addon are fairly small and self-contained, so I don't expect many conflicts. If you run into an issue, let us know in the Discussion page.
