Last Lego Star Wars game where the characters exclusively rely on mumbling and gesturing to express themselves. The next game, Lego Star Wars: The Force Awakens (2016), uses actual speech.
Before confronting the Geonosian Queen, the protagonists appear to consider whether to use against her a two-legged machine which is a clear homage to the power loader from Aliens: O Resgate (1986).
Though the game is based on seasons one and two of Star Wars: The Clone Wars (2008) television series, there is apparently a cheat to have Savage Opress, who wasn't introduced until season three.
