OMG-Z is a zombie-themed action puzzle video game developed by UK-based studio Laughing Jackal.

[1] Set in the fictional city of Redfield during a zombie apocalypse, the gameplay of OMG-Z focuses on causing chain reactions to eliminate the zombies.

Through the course of the game's 81 levels, the player is able to upgrade various abilities to improve their performance and achieve higher scores.

[3] Kristan Reed of Eurogamer viewed OMG-Z as "a monstrously addictive quick-fire affair that utterly nails what on-the-go handheld gaming should be about.

"[4] However, it has been noted by reviewers that releasing the game on the PlayStation mini format has limited the scope of the title and prevented the inclusion of features such as online leaderboards.
