This game looks fun, but I am not sure how many people I will get to play with if at all. What does this game offer in terms of single player content?

Excellent question!

So we're currently in alpha right now, so we've got our core gameplay loop but we're a little content light as we work out the unlockables system and getting Networked Multiplayer in. However, we have plans for a Story Mode that we'd like to achieve someday, and if not, we'd at least like to make some sort of single player content similar to how Smash Bros handles it. For the time being, you can play against the computers, and once we're done with the next update, there'll be an unlockable progression system that is single and multiplayer friendly :)

Also, we're open to hearing more suggestions on what would make it a more enriching single player experience for you, please let us know! :D
