Tower defense meets the Old West in Guns'n'Glory
Kudos to the developers of Guns'n'Glory for bringing a fresh twist to the tower defense game genre. Guns'n'Glory is set in the Old West, with you and your henchmen trying to keep wave after wave of settlers from making through the canyon, and safely off screen.
The game is also unusual in that you can move your defenses while the game is going on: Once the settlers have made it through your first wave of defenses, move your defenses to the end of the screen to shoot 'em up again. It takes a little getting used to the fact that the entire game level isn't on the screen at the same time, but it is easy to adjust and start swiping and pinching your way to Old West fun in this clever tower defense game.
