Question 1

Can friends work on the same factory?

Accepted Answer

Yes. Factorio supports online and LAN multiplayer as well as dedicated servers.

Question 2

Do mods need to match?

Accepted Answer

Yes. Players joining a modded server need compatible game versions and mod sets.

Question 3

Is controller support complete?

Accepted Answer

Steam lists partial controller support, so some interactions still work best with keyboard and mouse.

Question 4

Does Factorio require Steam?

Accepted Answer

No. It is also sold through GOG and the developer's own site; each player still needs a legitimate copy.
