In 1984, Scholastic published Bannercatch for the Apple II and Commodore computers. An edutainment game with recognizable capture-the-flag mechanics, Bannercatch allows up to two humans (each alternating between two characters in the game world) to play capture the flag against an increasingly difficult team of four AI bots. Bannercatch's game world is divided into quadrants: home, enemy, and two "no-mans land" areas which hold the jails. A successful capture requires bringing the enemy flag into one team's "home" quadrant. Players can be captured when in an enemy territory, or in "no-mans land" while holding a flag. Captured players must be "rescued" from their designated jail by one of the other members of the team. Fallen flags remain where they dropped until a time-out period elapses, after which the flag returns to one of several starting locations in home territory. The 2D map also features walls, trees and a moving river, enabling a wide variety of strategies. Special locations in the play area allow humans to query the game state (such as flag status) using binary messages.
