Known as Gradius in Japan – but Nemesis everywhere else – Konami‘s classic 1985 shoot ’em up is one of the earliest progressive weapons blasters, with distinct levels and boss battles.
The game is somewhat reminiscent of the classic side-scrolling Scramble (also by Konami), but in Nemesis you fly a ship called the “Vic Viper”, and which has a variety of different weapons which can be powered-up by collecting capsules left by destroyed enemies.
