Fasttrack and griffin-of-oz have unlocked all the new figures and reveals how their alt-modes look like in the game. These images will give a better understanding on how the toys will look like, save for minor changes.
New Battlepack Alpine Sideswipe and Strongarm is revealed along with several new Mini-Cons, Groundpounder and the new One-Step Evolved series.
2005 Boards Member Griffin stated:
[F]inally got around to taking some snapshots of the latest update, which only had 8 new bots and 7 new Minicons… so not a lot of photos this time.
On the Game’s character-select screen, “new” are completely new characters, while the ones with “!” on them have new versions added to existing characters.
