Smurfy's had listed a penalty to Gauss Rifles early, but removed it... I'm not sure if the data is not working, or if it behaving differently as intended.
From the game data (use 7-Zip or compression utility of your choice, to open up Gamedata.pak and look into the directories... ->Libs->Items->Itemstats.xml - use notepad or some text editor to open the file):
<WeaponStats Health="3" slots="7" type="0" projectileclass="bullet" numFiring="1" damage="15" heatdamage="0" heatpenalty="3.0" minheatpenaltylevel="1" impulse="0.05" heat="1.0" cooldown="4" ammoType="GaussAmmo" ammoPerShot="1" minRange="0" longRange="660" maxRange="1980" tons="15" duration="0.0" lifetime="10" speed="1200" volleydelay="0" groupedlocally="1" ExplodeChance="0.9" InternalExplosionDmg="20" maxDepth="10.0"/>
Apparently the Gauss Rifle is supposed to deal additional heat from "equipping it" (minheatpenaltylevel = "1") with a penalty of 3 pts (heatpenalty="3.0").
Compare this to the AC20
<WeaponStats Health="18" slots="10" type="0" projectileclass="bullet" numFiring="1" damage="20" heatdamage="0" heatpenalty="24.0" minheatpenaltylevel="2" impulse="0.1" heat="6.0" cooldown="4.0" ammoType="AC20Ammo" ammoPerShot="1" minRange="0" longRange="270" maxRange="810" tons="14" duration="0.0" lifetime="10.0" speed="900" volleydelay="0" gravity="0,0,-9.8" maxDepth="10.0"/>
The stats are what we know them to be... heat penalty is @ 24, and the # of AC20s to be fired at the same time to get the penalty is 2.
So.. I'd like to know if Gauss Rifles are unaffected or getting an indirect heat penalty.
Just in case... for people who didn't notice PGI's AC2 ninja heat penalty:
<WeaponStats Health="10" slots="1" type="0" projectileclass="bullet" numFiring="1" damage="2" heatdamage="0" heatpenalty="1.0" minheatpenaltylevel="4" impulse="0.0375" heat="1.0" cooldown="0.5" ammoType="AC2Ammo" ammoPerShot="1" minRange="0" longRange="720" maxRange="2160" tons="6" duration="0.0" lifetime="10.0" speed="2000" volleydelay="0" gravity="0,0,-9.8" maxDepth="10.0"/>
So, 4 AC2s can trigger the heat penalty (of 1).. however, it's not working the way it should as seen in various threads. I'm sure it is working as intended™.
