Devolver Digital, the publisher behind the Serious Sam franchise, is offering 100 Xbox Live Arcade codes for Serious Sam 3: BFE to those who publicly criticize the recently released Medal of Honor: Warfighter, according to a blog post on the publisher's website.

The Devolver post describes Warfighter as "yet another military shooter where cover is king and most folks spend their time peeking out from behind a wall or a strategically placed concrete barrier," adding that "that shit is weak."

To enter the contest users are asked to tweet about "the stagnant modern military shooter" using the hashtag #SeriousSam3XBLA, or by making a post on the Serious Sam Facebook page.

Serious Sam 3: BFE is available now on Xbox Live Arcade. The title was released last year to PC, while versions for PlayStation 3 and Linux are underway.
