More seriously I think Gauss should be overhauled to be the definitive 'armor penetrating' weapon.

Namely it ignores 50% armour (and maybe some Piercing resistance), but deals less damage.

If possible it would also be able to penetrate walls in the following manner:

#1: Gauss projectile connects with wall.

#2: Effective HP for purposes of determining whether or not it is destroyed is reduced by armour pen % (50). Gauss projectile damage is then applied to the wall.

#3: If the Gauss projectile destroys the wall, the post reduction HP per #3 is deducted from its damage. The projectile then continues on its merry way until all of its damage is absorbed by walls/targets.

The same process is applied versus a target: If the Gauss projectile overkills the target, it continues to travel after deducting the target's remaining health from the damage.

For example, a Gauss Musket deals 70 Piercing. It encounters a 60 HP wall. The wall's effective HP is reduced by the Gauss Musket's armour pen of 50% to 30 HP. The wall takes 70 damage and is destroyed. The wall's effective HP of 30 is deducted from the Gauss Musket projectile's power, reducing it to 40, and the projectile continues moving until it strikes and kills a Researcher with 30 remaining HP. The projectile's power is reduced by the Researcher's HP from 40 to 10, and continues to move until it hits a brick wall with 40 HP and fails to penetrate its effective 20 HP with 10 power remaining.

Basically you have Gauss weapons not unlike those awesome ones from Eraser, that are effectively inverse shotguns: most effective against low HP, heavily armoured targets, least effective against high HP low armour targets.
