I was gifted this game by the friend of a guy who plays TF2 with me. In retrospect, I'd buy it twice over.
This is a one of a kind, unique indie game that takes a bit of getting used to.
Regardless of whether you are playing local or online, the game plays in splitscreen (meaning you can see the point of view of the other players), much like local console shooters.
In this game, there are no world models. You are all invisible except for the occasional smoke trail.
This means to locate your opponents, you have to screencheat
. Look at their window to see where they are, and fire accordingly.
You aren't stuck with just guns either, you also get candles, hobby horses, crossbows, exploding teddy bears, and more of that wacky stuff. There are various gamemodes, ragdoll skins and such. Also, ragdolls don't disappear. You can play 10 rounds in a row and be drowning in ragdolls.
It supports local and online multiplayer and has controller support.
The only problem is that you will most likely need friends with the game to play it. I've yet to find a public server to play on, but this isn't a game fault.
tl;dr: unique game where everyone is invisible and you ride a hobby horse into them to win
