Crazy gaming time!
We're in control of a Dolph Lundgren dude with spiky hair and shades who must frantically clear 64 rooms infested by an array of nasties. He gets around using the screen's four sides and can escape the hoard by leaping across to the opposite side - but be careful because your shield won't last forever! Firing is constant and in the direction last used but can be temporally frozen by holding down the fire button <cough> Llamatron.
Visually, things are amateur but it works great with lots of silly sprites filling the screen. The audio is insane thanks to the DMA coprocessor pushing out funky samples to keep everything loud and exciting. Overall, this is one incredibly addictive and psychedelic shoot 'em up and I loved every zany minute of it!!
