In 1986 Konami released a hugely popular spin-off to the Gradius in the arcade. Building upon its inspiration, Salamander introduced co-operative gameplay and a simplified power-up system – all whilst providing the much loved shoot-em-up action. Three decades on it would appear that Konami originally hoped to celebrate this milestone with a HD remake for mobile devices. While this may not have materialised officially, a source online has since leaked a playable version of this unreleased update.
