Don't trust co-op – Crimsonland HD Review

I love this game, I play it on my own plenty. But I downloaded it for co-op play with friends. The game says you must purchase the full version to play co-op. I gladly did. After the option didn't show up, I discover that you need an MFI gaming controller to play with friends. I buy 1 controller to test the waters and it works pretty good (pairing can be a pain). I buy three more and get excited for some carnage... Only one controller goes active. The rest remain paired but useless. Why is this so hard, 10tons?
