A fine side-scrolling action game released in 1988 on the budget Rack-It label (for a mere £2.99), Battle Valley is a hectic mixture of tank blasting and helicopter flying, with a pounding soundtrack and solid graphics.

You basically drive a tank until you reach a hole in a bridge, then switch to the chopper to fly in some girders, then switch back to the tank again. Repeat until you eventually win…

If anything: Battle Valley could’ve done with a bit more colour (blue and brown were never the best of combinations – just ask Joe Strummer), although it’s still pretty amazing that this smooth and solid shooter fits into only 64K of RAM.

Well worth a play if you’ve never tried it before. Battle Valley is hidden gem on the Commodore 64.
