Originally imported from Germany by Anirog and now doing the rounds again with a different cassette insert.

You control a wedge-shaped flying machine which also doubles as a gun-cum-fortification marker. Dodging about behind barricades, you exchange fire with trundling armoured vehicles. These have to be weak before they crumble.

To keep the interest going, each armoured wave is of a different mark (I saw four types), yet the graphics are too small to be worthy of any attention in their own right.

At least the format is entirely distinct from the two-up Tank Duel efforts and does allow for tactics to be evolved.

This is a value for money shoot-'em-up with ten levels of skill.
