We've been revealed! ~~SFH2, enemy battle scan online.
Ah well, Rocky, you beat me to it.
According to the Sky9 developers, this is going to be a smaller game compared to their other ones, but it will have lots of replay value. It is going to be a running game at core, but there will be shooting and other "twists and turns," according to Juice-Tin. More specifics on the devices: It is designed for iOS, Android, and Blackberry, so pretty any portable device is compatible. It will most likely have all of the classes from SFH2, so you'll see the Engineer, Mercenary, General, Sniper, and Juggernaut. Also mentioned was that there would be weapons, skills, and upgrades, so it will have a lot of the things that SFH2 had. When released for mobile devices, it will cost about $1-2, so nothing expensive. The Flash version later on will be free though.
