We can't wait to play online with you!
Playing online will be a quick, smooth experience for all!
One item of note: we do use Steam's P2P networking and listen server functionality to run ShapeRockets. For 99% of you, this will all run fine as expected automatically!
In test, while rare, we found some routers have ports closed that need to be open for ShapeRockets to find games. But it's a quick and normal thing to tweak. So if for some reason you have one of those rare routers, simply refer to this Steam page and you should be ready to go!
