Back in the 1980s, children were riveted to their television sets to watch the ongoing battle between the Autobots and the Decepticons. The "robots in disguise" became a sensation, and one of that generation's most popular catchphrases was the animated series' famous battlecry, "Autobots, roll out!"

　　The man behind that line is Peter Cullen, who voiced the Autobot leader, Optimus Prime. Also lending vocal talent to the show was Frank Welker, who provided the raspy voice of Decepticon leader Megatron.

　　Today, Activision announced that both Cullen and Welker (pictured above) have signed on to reprise their roles in the publisher's upcoming Transformers: The Game, based on the DreamWorks Pictures and Paramount Pictures film Transformers, due out in early July.

　　"As Transformers fans, we knew the importance of having the well-known voices of Optimus Prime and Megatron in the game,” said Activision head of production Laird Malamed.

　　In addition to sending shivers down the spines of kids as Megatron, Soundwave, Buzzsaw, and other Transformers, Welker has done voice work for The Simpsons, Kingdom Hearts II, and New Super Mario Bros. and Mario Party 5 as Bowser. Cullen also provided the voices for fellow Transformers Ironhide and Slugslinger and the sheepish Eeyore of Winnie the Pooh fame.

　　Transformers: The Game will be released on multiple platforms this summer. Traveller's Tales is developing the PlayStation 3, Xbox 360, Wii, PlayStation 2, and PC versions, Savage Entertainment is developing the PlayStation Portable edition, and Vicarious Visions is working on the two DS versions.
