Game developers initially struggled to bring "real" gaming experiences to smartphone, but it looks like the traditional first-person shooter genre is doing just fine. Over the past week, both Modern Combat 3 and Frontline Commando arrived on Android (they're also on iOS), and both look poised to raise the bar for smartphone shooters. Just like how Shadowgun showed us a Gears of War clone could bring a beefy space marine and cover mechanics to the smartphone space, Gameloft's Modern Combat 3 ($6.99) is an unabashed homage to Call of Duty, with a huge 1GB+ download's worth of impressive graphics, while Glu's Frontline Commando is a free-to-play third-person shooting gallery with destructible cover. Check out the videos below, and if they look interesting, find them both at our source links.
