Frazzle

The player's star fighter has become trapped by an energy barrier, surrounding the playfield on all sides. The culprits, a gaggle of aliens known only as the Beasties, have now endeavored to warp inside and finish the job by ramming their prey to death. What's a fighter pilot to do? Luckily, you're equipped with an inexhaustible supply of energy bombs which can be dropped behind your ship, armed and ready to blast any encroaching alien bastard to kingdom come.

The bombs must be carefully placed to intercept the Beasties as they rampage around the arena, bouncing off the surrounding force field. Your ship can make instant 90-degree turns, and accelerate or brake as needed for emergency moves - any collision with an alien, an energy wall, or your own mines results in grisly death. Although ammo is infinite, only a limited number of bombs can be deployed at a time, so don't just go mashing that single button on your dashboard.
