G'day Newtonians,

We're currently testing an online co-op release of Newtonia.

To help us test, you need to change to the 'netplay' branch of Newtonia.

  1. Right click on Newtonia in your steam library games list, and click Properties

  2. Click "Game Versions & Betas"

  3. Select "netplay"

  4. Close the Properties window

  5. The game should now queue an update, which will install the netplay branch

Then, a new option "Online", should appear on the main menu. One player should be designated the host, and the second player is designated the client.

As the host:

  • Select Online on the main Newtonia menu

  • Select Host

  • A 5 character room code will appear on the screen, it will automatically be copied to your clipboard

  • Paste/type/tell the code to the second player

As the client (second player):

  • Select Online on the main Newtonia menu

  • Select Join

  • If you have copied the 5 character room code, newtonia will detect and auto-fill the value, otherwise type in the 5 character code

  • The game should join the host automatically after typing the code

Then simply enjoy your co-op experience!

Pause (P) works for both players, but only the host can toggle friendly fire (G). If the second player disconnects, they can rejoin using the same steps listed above (the host will display the code on the top of their screen if P2 disconnects). Unfortunately if the first player leaves the game the progress is lost.

Feedback is welcome during this time of testing, and I hope to release it to the main branch soon, I'm just ironing out bugs that can occur when both players have difficult network conditions (restricting NAT for example).

Let me know how it goes!
