Xari Arena
• EASTER EGG: After completing level 32 there’s supposedly a message that tells you to send a picture to the master of the arena, and it lists Atari’s address.
• At least 7 prototype versions exist, all in various degrees of completion. The latest, dated 9-20-83 is the final version according to programmer John Sehgers and the only one that supports the Trak-Ball.
• BUG: In the later version, sometimes a Xari will get trapped in the well and will become invincible, and since you can’t shoot a Xari inside the well, you can’t finish the level.
