Hulk was originally planned to be a playable character, and would have been unlocked during the Omega Base mission after a gamma explosion caused Bruce Banner to transform. According to director Dan Vondrak, there were a lot of back and forth talks between Marvel and Raven Software regarding his use, but due to licensing issues with Vivendi Universal (who acquired the video game license for the character to help promote the 2003 film "Hulk"), the playable Hulk and a Comic Mission for him were scrapped from the game three weeks before its release. Moon Knight replaced him in the PlayStation 3, Wii and Xbox 360 versions of the game. Despite this, Hulk appears as Bruce Banner during the Omega Base mission, likely a leftover from development, and during the "Doom's Day" cutscene. Hulk was later released as DLC for the Xbox 360 version of the game in May 2007, which Vondrak suspected was only then approved by Marvel to help promote the 2008 film "The Incredible Hulk".
