So far as I know, AC2's only are supposed to generate penalty heat when a mech mounts 3 or more of them and fires them at the same time. However with this atlas I was only mounting 2 and firing them at the same time.
To accomplish a stagger fire effect and repruduce the bug I am speaking about, try putting each AC2 on a seperate fire group then firing and holding down one roughly half a second before firing and holding down the other. This was fun as it generated a nice stream of autocannon fire, but it also sent heat levels into OMGWTFBBQ!! levels within just a few seconds. I can not believe this is working as intended. Therefore it must be a bug, so I am reporting it here. =)
*Edited because I wanted to put in the 'omgwtfbbq' item. It is so rare that anyone really gets to use that line and have it apply properly to the conversation... I just had to add that in.
