French mobile game developer In-Fusio has sued Microsoft, accusing the company of breach of contract over the mobile version of Halo. In-Fusio announced at the 2005 CTIA IT Wireless and Entertainment trade show that it would bring the blockbuster sci-fi shooter franchise to mobile phones as part of an exclusive three-year deal with Microsoft. More than a year after the initial agreement and with no Halo game available for mobile phones, In-Fusio filed suit against Microsoft in U.S. District Court in Seattle last month, charging the company with refusing to approve game designs while still demanding payment for an exclusive license.
