Upgradable weapons???

If I just heard correctly I heard that people can somehow can upgrade their primary weapons...how is this done with heavy please please please tell me!!!

As far as I no the upgraded weapons aren't available yet (unless I missed and update).

What you've probably heard is about is the load out of new weapons for each class.

ya lol thats probably it thanks for clearing up the confusion. 

Well since you started this topic, mind if I change it around a bit?

Well there has been discussions about the load out of new weps for each class...how about the HWG???

Something biiiiiig and nasty.  How about GLaDOS?

Concepts for Minigun Loadouts (replace minigun with...):

• Cannon - It's big and vicious enough to warrant a heavy having to lug it around.
• Mortar - As cannon, but more long range oriented, with an arc.
  
• Railgun - Adjust as you see fit.  Fires a single, precise shot with extreme recoil, high damage and a small-ish explosion at the target location.
  
• Gatling Gun - As minigun, but stronger for long range, with a small chance of jamming.
• Chain Gun - As minigun, but spread of fire is more precise, slightly less damage, more ammo per clip.
• Vulcan - Heavier, meaner, but slows you down more.
• Microgun - Lower damage, but you can jump freely & move faster while you're spinning it.
  

Shotgun:

• Rifle - slightly more powerful version of sniper's assault rifle.
• Ballistic Shield - Replacing the shotgun with a shield that protects against shots, flames and splash damage coming from a certain direction.  Heavy as a tank, barrier or just helping him get into position with that bald head intact.
  

Fist:

• Boxing Glove - Punches are faster, lower damage, and knock enemies back, screwing up their aim.
  

The railgun and rifle might overlap too much with the role of the sniper. I do like the shield idea for the heavy though, it'd definitely create interesting strategies. Not so sure how'd Valve'd make it fit with the whole Wild Wild West/Steampunk style of TF2.

>> The railgun and rifle might overlap too much with the role of the sniper

Possibly so, but it's like comparing the scout and his scattergun with a shotgun wielding pyro.  The Heavy is less about bunkering down and making surgical strikes, and more about being a huge, mean damage dealing machine.  He can't be nearly as efficient or accurate about sniping targets, but instead gets into position and starts blasting.  With the railgun potentially having a delayed fire, (1 second between click & the following blast) it would play very differently from the sniper rifle.

I really liked the shield idea actually though fighting soldiers (the heavy bane in my opinion) would become different. 

The shield idea was proposed for the Soldier a while ago, and I thought it quite silly.  But, the same option for Heavy doesn't seem that bad, it could be interesting.  While using the shield he should have severe penalties like the mini-gun, such as very slow motion etc.
