At first sight, Commandos might seem like a classic real-time strategy game, but you soon discover that it's more a puzzle-tactical game, with mechanics heavily based on stealth. It is set during World War 2, and it includes scenarios in North Africa and Europe, with missions that vary from assassinations, sabotage, or rescuing other soldiers. This first game, designed by Gonzalo Suárez and Ignacio Pérez Dolset, was released in 1998 for Windows only. Commandos: Behind Enemy Lines is the first chapter of a famous tactical game series created by the Spanish studio Pyro and published by Eidos.
