Hi everyone!
I did every test I could come up with for the new system.
If Steam P2P back-end behaves like it's supposed to, the game works 100%.
Sometimes there might be some mis-synced positions due to some latency, but those will be synced in a specific timeframe between shots to correct any discrepancy.
So, the P2P Build was pushed to the default branch and it's now available.
Hope you enjoy!
