Here's why:
* He's a Decepticon: Thundercracker is a loyal Decepticon, not an Autobot. The game focuses on the Autobot side of the war.
* Game Exclusive Characters: While the game features several original characters, Deception Thundercracker isn't one of them.
Where You Might Find Thundercracker:
* Transformers: War for Cybertron - Decepticons: This is the other half of the game, focusing on the Decepticons. Here you might find Deception Thundercracker.
* Other Transformers Games: Thundercracker has appeared in several other Transformers games, so he might be playable in those.
Please note: If you're looking for Thundercracker specifically, you'll need to look for him in games or other media that feature Decepticons.
