Challenging and very intense co-op twin-stick shooter. Enemies and levels will properly test team compositions and loadouts. Friendly fire is pretty brutal in this game since in hectic moments you can easily wreck your teammates...unintentionally or not. Solid game to play with friends, either to tryhard or just mess around with and laugh at the chaos. Can't say much about the solo experience, but that's not really the focus of this type of game.
