Does Risk of Rain have Local/Offline multi-player or only Online?

And if it does, how does it work? Split-screen?

Can 2 players use the same keyboard, as in the old games?

I have done further testing and I would say no, strangely. That is because if my gamepad is conected, I can select the control device for player 1 (keyboard chosen), but when the player 2 is to be selected, the gamepad option is locked and cannot be changed. I unplugged the controller and I could select to control both players with keyboard, but only one control scheme is shown and both players seem to be a single entity.

So, even if I find very weird it could not be configured (and I haven't investigated a lot because of I play alone), as far as my today's knowledge, I must say 2 players cannot play using one keyboard. I'm glad I could help you :3
