This game was made out of a passion for playing with friends. The market for local multiplayer seems a little underserved on the PC platform. This game strives to help promote couch games on PC. Hopefully, there will be many more games aiming at couch gaming for the PC. Online gaming is great fun, but it ain't the same as having a sit-down with your friends and tell them to their face how much they suck at video games! However, playing online can also be fun, so now you can mix and match meaning that you can play 1, 2 or 3 people on the same computer and the rest of the players can do the same on another PC connected to the internet, combining couch and online play.

A little practical info:
This game is built for Wired Xbox 360 controllers or Wireless Xbox 360 controllers with a wireless receiver adapter for PC. Xbox One controllers ought to work just fine. PS3 and PS4 controllers can be used with Xinput drivers/wrappers. Other controllers that are Xinput compatible should also work.
