Updated: Metal Slug Series
Good news, classic arcade game fans: the entire Metal Slug series now supports MFi controllers on iOS!
While Metal Slug 2 and Metal Slug 3 previously supported MFi controller input, the other games in the series did not. Thankfully, SNK Playmore and Dotemu just fixed fixed that.
Unfortunately, these games aren’t playable with Bluetooth controllers on iOS8, due to the previously documented bug (seriously hoping for a fix from Apple on that). But all gamers on iOS7, and gamers with the Moga Ace Power and Logitech PowerShell on iOS8, will definitely want to give this one a look.
