Herzog Zwei is a real-time strategy game developed by Technosoft and published by Sega for the Sega Genesis. Released in both the USA and Europe, it's known as a foundational title in the real-time strategy genre. The gameplay involves resource management, base building, and real-time combat. Players control a combat unit, expanding their territory and destroying opponents. The European and US versions will likely contain regional differences in terms of manual, potentially localization, but overall, they should play almost identically.
