Spar Torpedo Rules

Brigade have released rules for the Cutlass Spar Torpedo:

The Spar Torpedo is a fairly suicidal aerial weapon currently used only by those most desperate of adversaries, Sky Pirates. A craft designated as a Spar Torpedo vessel must manoeuvre so that it is within 2" of an enemy vessel, and the enemy vessel is in its front arc. It may then detonate the torpedo, causing 1d6 damage to the target (re-rolls apply on a '6'). If the die roll is '1' then the weapon is considered to have back-fired - the target still takes 1 damage point, but the carrying vessel takes 1d6 damage itself. The spar torpedo is a one shot weapon.

Thanks gents!
