Namco Bandai titles include Test Drive Unlimited 2, Enslaved Odyssey to the West and Splatterhouse.
Brands2Life will use a combination of traditional, interactive, social media and guerrilla PR tactics to promote the brand's top titles in the UK. The agency will also work on the firm's extensive range of smaller titles.
Brands2Life co-founder Sarah Scales will head the retainer. She said: 'We are excited to be supporting Namco Bandai's entire portfolio.'
