I have been working on bringing multiplayer to Aquila, and put together a relatively short video showing it in action. It can be seen below. I'm 'flying' both birds, so controlling one while the other is on autopilot, and then editing the videos afterwards.
If you are interested in giving it a try, when it is ready, please comment below. I anticipate setting up a server here at home, with appropriate port forwarding, perhaps with an associated chat server, at an appropriate time and we'll see how we go!
I believe Aquila's traffic requirements to be low, as prey items are not implemented yet. Mirror, the networking extension I am using for Unity, is MMO capable ... so you'd think a high number of players would be possible in theory? I've set a limit of 16 on my development version.
Anyway, if you are interested please reply back here. I have no ETA for such a test at this time, but not too long. :)
Thanks;
Graeme
