Duel! is a game written by Juergen Schroeder and published by CodeWorks - Cursor, a company known for developing software for the Commodore PET. The game was released during the early 1980s, a period when the Commodore PET was a popular personal computer for both educational and home use. CodeWorks - Cursor specialized in creating games and utilities for this platform, often focusing on simple yet engaging gameplay mechanics.
Duel! is a two-player game, as the name suggests, and involves a competitive or dueling scenario, though specific details about the gameplay mechanics are scarce. The game was likely designed to take advantage of the Commodore PET's keyboard input, as the system lacked a joystick port, making it suitable for turn-based or simultaneous keyboard-controlled gameplay. The graphics, typical of early PET games, would have been character-based due to the system's limited graphical capabilities.
The game is relatively obscure today, with limited documentation or preserved copies available. It is part of a larger library of Commodore PET games from the early 1980s, many of which were simple, text-based, or relied on ASCII art for visuals. CodeWorks - Cursor's contributions to the PET software library are remembered by retro computing enthusiasts, but Duel! remains a lesser-known title in their catalog.
