Combi-grenade

"A Weapon with this Special Rule can fire multiple profiles simultaneously."
Each time a Model makes a Shooting Attack with a Weapon Profile with this Special Rule, the Controlling Player can select another Profile from the same Weapon with this Special Rule and make attacks with it as part of the same Shooting Attack. Note that if that Profile also has the Limited (X) Special Rule, this does not allow it to be selected to make attacks more than the number of times equal to the value of that Special Rule.
