An early title was "Transformers Armada: Prelude to Energon"
Bonus storyboards reveal that seven levels in the game were originally planned as just three: Amazon and Deep Amazon were one level, explaining why one ends on a hill and the other starts on one; Antarctic, Alaska and Starship were a single level with Demolishor as the boss, and Pacific Island and Mid Atlantic were one level.
Many of the lines of dialog are paraphrases or direct quotes of lines from the 1986 Transformers movie. Examples include most of Optimus Prime's selection speech, and Megatron's 'I would have waited an eternity for this! It's over, Prime!' during the introduction.
Several characters were cut from the final game, most notably Tidal Wave's Minicon Ramjet as a mid-stage boss and Demolishor as boss of the Antarctic super-level.
While they don't use them, most of the Decepticon bosses are seen with their Mini-Cons attached.
