Is there a way to play co-op via internet?
 

I love this game and I was trying to play it co-op but it's really hard to play with 2 people on the same keyboard. I was wondering if there was a way to play Co-Op over the internet. (There's battle, capture the flag, why not co-op?)

Thank you

Yes, that's easily doable. Download and install the JJ2+ patch from J2O, host online and do /gamemode coop.

You need to start an online server first(In any gamemode), but yeah that's basically it.

(Although it is slightly buggy at times)
