Exerizer / Sky Fox
Exerizer is a vertical shooter from Jaleco
The game can be played by up to two players in alternating turns.
At the player's disposal to fight the approaching enemies, some of them made in pseudo-depth 3D
graphics with scaled sprites, is a small space fighter capable of firing two types of projectiles:
the unlimited but slow rockets and the fast laser shots that are limited by draining the
ship's power. The power can be refilled and the ship itself upgraded by collecting the power
ups that appear after destroying certain enemies.
