The current rules relating to weapon skill is a little more restrivtive than I would like it to be. As such I have made a change to it. Thie new rule will be as follows:

Weapons \x {2013} Each combatant is only allowed to use the weapons that he officially brought into battle. You may not conceal and use any weapons. At the beginning of the battle, the judge will announce the weapons each have selected to bring into a battle. Skill in some weapons grants skill in related weapons as well. A slug-thrower weapon is similar in usage to a blaster.You are allowed to use weapons in which you have no skill, however you are untrained in the use of such. Penalties will occur for unrealistic use of such weapons.

Expect it to be updated on the rules page soon.
