If you own a gaming-capable PC and haven't played Transformers: Devastation, Transformers: War For Cybertron, or Transformers: Fall of Cybertron, you're in luck! Valve's Steam downloading service is holding a sale from now to the 19th of this month on Activision's Transformers titles for the PC platform: Devastation, FoC, and the poorly-reviewed Rise Of The Dark Spark are each $9.99 in the US, while WFC will set you back $5. Each of those is easily worth the amount involved... except maybe Dark Spark. Keep reading for a link!
War For Cybertron and Fall Of Cybertron are High Moon Studios' excellent third-person shooters, set in the Aligned Continuity but having (particularly in the first game, WFC) a certain level of G1 influence. But if you really want G1, Transformers: Devastation is a "stylish action" brawler/platformer from famed Japanese developers Platinum Games.
