Atari today announced that Sean "P. Diddy" Combs, Rosario Dawson, Brittany Murphy, George Hamilton, Giovanni Ribisi, Adam West, Andy Dick, Charlie Murphy, The RZA, and Michael "M.C. Serch" Berrin will all add their voices for the characters featured in Marc Ecko's Getting Up: Contents Under Pressure. Set in the city of New Radius, the game will offer a world where freedom of expression is suppressed and graffiti has been outlawed by a tyrannical government. You play Trane (voiced by the hip-hop artist Talib Kweli), a graffer who must use his talents in order to expose an oppressive mayor and rid the city of his stranglehold on New Radius. Developed by The Collective, Marc Ecko's Getting Up: Contents Under Pressure is slated to release this fall for PS2, Xbox and PC.
