Due to the nature of Doubles games, certain rules (such as game end conditions and what is required to fulfil certain Common objectives) change slightly. Below are the key changes from standard matched play games for use in Doubles:

Break Point

If the Break Point game end condition is being used at a Doubles event, work out the combined Unit Strength of both players' forces to determine the break point of their army overall.

The King is Dead

When scoring the 'The King is Dead' Common objective at a Doubles event, if the enemy General of the Primary force has been slain, has fled off the battlefield or is fleeing when the game ends, you win a bonus of 100 Victory Points. If the General of the Secondary force is slain, has fled off the battlefield or is fleeing when the game ends, you win a bonus of 50 Victory Points.

Trophies of War

When scoring the 'Trophies of War' Common objective at a Doubles event, you win a bonus of 50 Victory Points for every enemy standard claimed as a trophy, as described on page 200 of the Warhammer: the Old World rulebook. Additionally, if the enemy Battle Standard Bearer in the Primary force has been slain, has fled off the battlefield or is fleeing when the game ends, you win an additional bonus of 50 Victory Points. Lastly, if the enemy Battle Standard Bearer in the Secondary force has been slain, has fled off the battlefield or is fleeing when the game ends, you win an additional bonus of 25 Victory Points.
