The three-year agreement covers ten games based on characters taken from the Hanna-Barbera studio licensed to Eidos by Warner Bros. Interactive Entertainment.
Eidos and Deadline previously worked together on Total Overdose and its PSP spin-off Chile Con Carnage.
Characters such as Tom & Jerry, The Flintstones, Yogi Bear, The Jetsons and others are to get the game treatment thanks to the studio, which is based in Copehagen.
The titles will be produced for a variety of platforms.
The studio has other projects in the pipeline, too; in an official announcement company bosses said the development demand has created a need for "significant expansion" of Deadline Games' operation.
