THis is what I thought a cool sniper would be:
cost: 4cp Range: 15' UR 4 Dmg 1d6-2
The trooper using the sniper rifle, for a +2 CP cost, can use the Critical hit power: If you roll a critical success when rolling for skill, the sniper has scored a Headshot: the enemy's head is completely blown off
Heroes would get the Crack Shot special attack for +2 cp: Instead of making a normal attack with a ranged weapon, your hero may attempt to use the Crack Shot special attack. The owner rolls 1d6. On a roll of 6, the targeted figure is instantly destroyed, on 2-5, the attack misses. On 1, a critical failure.
The Crack Shot attack is for all ranged weapons because heroes watch so many crappy Western movies that they think they can make an impossible* shot, and, in the end, may actually succeed.
