In the Zinglon's Ale mini-game, players must try to gather as much ale as possible, while dodging wave after wave of bouncing enemies, and clearing the screen of enemies fully before advancing to the next level. If not cleared, the game continues infinitely while growing ever harder. Zinglon's Squadrons is a mini-game similar to Galaxian or Galaga. Large formations of ships fly down to attack. Individual ships in the groups break off to fly down in various ways. Players must destroy the whole fleet to advance to the next fleet. In the mini-game Zinglon's Revenge a giant ship projects a horizontal field of energy. Small enemies fall down from above and bounce around the edges of the screen and against the energy field. Touching the field or one of the small enemies could be deadly. Players must shoot all the small enemies to advance to the next level.

Brandon wrote a proposal document and sent it to the two leading shareware game publishers of the time, Epic MegaGames and Apogee. However, the game lacked any sound or music, and the graphics were "definitely not professional". As such, "neither got overly excited", but both showed interest.

However, after a long wait, Robert Allen—head of Safari Software—considered Tyrian to fit perfectly with their company, which handled smaller scale projects. Robert Allen had word from Cliff Bleszinski that Tyrian was very similar to Zanac, thinking that it should be followed up. Robert Allen gave leads to sound coders and artists, the first being Bruce Hsu who created interface graphics and character faces. Artist Daniel Cook was hired after composer Alexander Brandon showed interest in his artwork, which was—unbeknown to Cook—"sent around" by a friend. After he was
