In an interview with Scrawl FX Techland's Blazej Krakowiak confirms they plan to release a demo for the upcoming Call of Juarez: The Cartel.
He is unsure whether they will be able to bring out the demo before the release of the game, but the idea is to let players taste the new co-operative features of the campaign. Call of Juarez: The Cartel features co-operative play for three players.
