If you had your fingers crossed given recent news that The Amazing Spider-Man 2 ($6.99) was getting an offline mode that Modern Combat 5 would be getting the same treatment… I’m sorry to disappoint. As Gameloft_Ryan points out on our forums, the game is still going to have an online connectivity requirement due to the unified progression system.
It makes sense, really, and with so much multiplayer emphasis in MC5 of course they want to keep everything as fair as possible via online authentication. Historically speaking in the gaming world, when you’ve got a local profile linked to any kind of progression that you can also take online, various trainer hacks break that pretty hard for non-cheaters. (As veterans of the original Diablo and countless other games can attest to.)
But, really, with how much awesome multiplayer they’re packing in to Modern Combat 5, this is definitely a game you’re going to want to play online anyway.
