Bronze Award-winning slidy third-person shooter Epoch 2 has had its price on the App Store slashed down to nothing at all, which we can all agree is pretty darn cheap.
The game sees you playing a robot in a dystopian future. You're the only good robot, and you're tasked with shooting every other automaton to bits. You slide around from cover-point to cover-point, blasting everything that has a shiny metal face.
At review we said "There's a solid touchscreen shooter here, but Epoch 2 doesn't quite hit the right marks."
Still, for free you can probably forgive it a few missteps. You can grab Epoch 2 right now from the App Store for nothing at all. And if you fancy some robotic violence it's definitely worth a look.
