Wardog

Wardog is a cancelled PC game by Rebellion Developments Ltd. It was to be a third-person action based on the 2000AD comics.

Plot
Jack Wardog is a slave who has had his memories erased and an explosive placed into his skull. Should Wardog fail a mission his head literally explodes. This is to ensure his loyalty to the Endtrail Enclaved.

Your quest is to uncover your past for you are surely framed for your crimes.

Gameplay
Combat would be real-time with some turn-based functions aiming at individual parts of your enemies. You can harvest silicon from enemies providing you haven't shot at it and destroyed its value. The advanced AI made for complex battles, and as such you can trick enemies into fighting each other.

There are missions that are on a timer with his head exploding should the time expire.

The game was originally an third-person shooter with over-the-shoulder aiming. Then around 2002 the game was shifted to have an isometric viewpoint.

Cancellation
Wardog was cancelled around 2003 or so for unknown reasons. All that was released were the tie-in comics from 2000AD.
