Z-Raid fantastic River Raid remake. This game, like many shot'em ups, is about blowing up lots of stuff.
You fly your plane over the river which is divided into sections, with a bridge at the end of each section.

You will encounter islands, bays and narrow channels. Blocking your path along the way are enemy jets, destroyers, helicopters, submarines and bridges.

You lose your jet when it collides with the river bank or one of the enemy crafts or when you simply run out of fuel.
