Gnop! was the first computer game created and published by Bungie Studios. It was a simple Pong clone written and released nearly 20 years after the original. The name Gnop is simply Pong spelled backwards. The game was created by Alex Seropian in 1990, almost a year before Bungie's official incorporation. The game did prove popular enough among Mac gamers since the game was a free, user-friendly alternative. However, some fans were willing to purchase the source code, which Bungie offered for $15 (USD).
