Tyrian

A shoot em up where you fight a megacorporation whose name is just a few letters off from a certain company, while flying in a ship designed like a carrot that uses bananas as ammunition.

Unused music
Track 19 in the jukebox, The MusicMan, is part of the Loudness Sound Library used by the game.

"None"
"None" options exist for all types of items, though normally only Rear Weapons and Sidekicks use them. The options work fine for the most part (although flying around without a generator isn't the brightest idea), but attempting to select the "None" ship will cause the game to crash.

Miscellaneous Option Weapons
Weapon number 16 is an odd, unused assortment of firing modes. Power levels 1, 2, 5, and 7 are used by sidekicks, but power levels 3, 4, and 6 are unusually weird (and normally unused) firing modes. The last four power levels, however, are copied straight from the previous weapon, the Rear Vulcan Cannon.

HXS Class C Shield
The Class A and B variants of the HXS shield are used, but the C class variant is never purchasable in any location in the game. It can be obtained via ShipEdit, however.

Unused graphics
An unused icon can be found in the game data. It looks like some weird metal thing with a medical cross on it

Version differences
1.0 was the first release of the game, featuring 3 episodes. 1.1 was a bugfix.

2.0 added a fourth episode, An End to Fate, Super Tyrian and a few additional levels to Episode 1.

2.01 fixes some bugs, and adds a "Christmas mode" easter egg.
