11/9 Two
Content Warning:
This game is a parody of the September 11, 2001 attacks on the World Trade Center, a real-life terrorist attack in which almost 3,000 people were killed, in which the World Trade Center is rebuilt as a mall a thousand years later and history repeats. The evil mastermind behind the attacks is then revealed to be Adolf Hitler. The game ends with the protagonist imprisoned and "the sixth reich rul[ing] supreme" [sic].
Bug:
The first board of gameplay after the intro freezes ZZT as soon as the player takes a step. This is caused by a rare ZZT infinite-loop bug triggered only if the centipede follower values of both the player and a centipede head on a board happen to be 0, as a result of ZZTAE v1.0.3 (the tool used to make this world) setting leader and follower values to 0 for every statted element in a board regardless of its type. To fix this bug, the board must be edited with a different program to change the player's follower value to -1. In addition, the centipede head and segments on the board must have their leader and follower values changed from 0 to -1 in order for them to function properly.
