CTF 2187 (also known as CTF2187) is a closed-end, computer-moderated, play-by-mail (PBM) game that was published by Advanced Gaming Enterprises in the 1980s. It involved teams of robots, of varying size and capabilities, battling on a hex-grid arena with the purpose of defeating the opposing team or their command post. Players assumed the role of a battle robot pilot. The game was tactically-focused, with combat action beginning on the first turn. Games lasted 5–10 turns, or about six months. Players began at the rank of cadet but could spend experience points earned from a completed game to increase in rank (or statistics) for future games, up to the rank of General.
