Take the film 300 and substitute monsters. Monster Burner turns your fingertips into lethal fireball launchers. Like a maniacal wizard, you'll launch burning rocks at hordes of monsters as they storm your castle. Or tower. Whatever it is, it resides just off-screen.
For taking out combinations of monsters, you'll be awarded different amounts of coins. Sure, you can use the coins to purchase fun upgrades like slowing potions and fire walls. Or you can put down three fingers at once and hurl triple fireballs of doom!
We did notice that Monster Burner really wants you to enable Open Feint. Like really, REALLY wants it. Some menus have multiple 'enable' buttons on the same screen, and the game is constantly throwing popups about it in our faces. If only there was a built in service for this purpose. A 'Center' for 'Games,' if you will. Too bad we don't get to chuck fireballs at the menus.
