Hi. Is Door Kickers (2014) multiplayer?
* It doesn't have the "Multiplayer" label
* But it also says: "Notes: Online Multiplayer requires Galaxy authentication."

Which one is it?

It has co-op multiplayer mode (as the gamepage states), which requires Galaxy. It works, I checked it out some time ago.

@zeffyr, thanks, appreciated! So it doesn't have the "multiplayer" label because.. you can't play _against_ each other? Or I wonder why, maybe a mistake?

That's right, you don't play against each other, you cooperate to fight together with the bad guys :)

Nice, thanks for the response!
(belayed, but still)

MultiPlayer means MULTI PLAYER. It does NOT mean PVP. It only means more that one person can be involved in gameplay process.

Multiplayer is comprised of various players interactions:
PVP
PVE
PVPVE
Leaderboards competition (for various modes)
