Hi Ravyne, Thanks a lot.
Warrider is going to be single player only. We would love to add a multiplayer mode but unfortunately, we are a very small team and multiplayer means an awful lot of work to do. So no multiplayer until we get a larger team and a big budget!
We have not found a publisher for the game yet, therefore I can not comment on the price. The publisher will probably set the price as they see fit.
