In an era when talented lone programmers could quickly churn out top-notch, technically amazing titles to order, the arrival of Stavros Fasoulas' second horizontal shooter, Delta, came as no surprise. Yes readers, we were spoiled rotten back in 1987.
Riffing on the progressive power-up system employed in the big-name Japanese horizontal scrolling shooters of the day, Delta brought the concept to the C64 in as slick a fashion as anyone had attempted at the time.
Just like Nemesis/Gradius and R-Type, the game relied on your ability to memorise and wipe out wave upon wave of enemy attacks. Doing so would grant you a crucial power-up, which generally equated to speed-ups, and various forms of bolt-on weaponry of progressive power. It's a lovely formula, if a complete and utter rip-off.
