Transformers: Decepticons

Transformers Decepticons is an action-adventure video game based on the 2007 live action film Transformers.
It is one of the Nintendo DS ports of Transformers: The Game, but follows a different storyline with 20 missions that focuse exclusively on the Decepticons.

The game has local multiplayer for up to 4 players and had an online multiplayer mode called AllSpark Wars, a weekly competition between players using points from challenge missions for control of 7 AllSpark fragments. It required a separate account but had a clan system and online community forum.
The online component and community site were managed by Agora Games, now WB Games New York.
