N.O.V.A was a popular FPS game for iOS, which then crossed over to Android as well. And now droid-land is getting a taste of the sequel Near Orbit Vanguard Alliance. Not only that but Gameloft was kind enough to make the game available on Facebook too. The game has been around of iPhones and iPads for some time now (December 2010) and offers truly immersive gameplay, worthy of a hefty portion of your day.
First-person shooters, for me personally, are not the most comfortable genre to play on a phone, be it an iPhone or even an XPERIA Play. Now tablets are a whole different story all together as they offer a much larger screen, which is a must-have for me. Still you can give it a go if you are up to paying $5 for it.
In-browser playing is not bad too.
Here is a demo video of the game. Its for the iPhone version, but things are practically unchanged, so enjoy.
