We called Resogun "a smart, merciless little shooter" in our four-star review, but did you know that it's also a smart, merciless little shooter that can be enjoyed in online co-op mode? Yes, with another ship at your side, the fun can be doubled. You can get a taste for co-op thanks to the trailer above, and if you're a PS4 owner already, you have a couple other options.
Since the game is free for PlayStation Plus members - which everyone can try out thanks to a 30-day trial voucher - there's no reason not to check it out. And if you're worried about not having anyone to play with, don't be: One million PS4 units were sold during the system's first 24 hours on the shelves, so it shouldn't be too hard to find a co-pilot.
