It seems that Frontline Commando may be the next big breakout hit on mobile devices! In addition to offering free gameplay, the game allows users to build and customize their own character and load their very own weapons. The game is completely free to download for both iOS and Android right now. Last week, Neogaf published an intriguing teaser for their upcoming game called Frontline Commando: D-Day (which will also be available on iPhone).
