3 days after Helldivers 2 dev's CEO denied the existence of heavy machine guns, they now exist: Introducing the LAS-99 Quasar Cannon and the MG-101 Heavy Machine Gun

pcgamer.com:

Earlier this week, the CEO of Helldivers 2 studio Arrowhead Games flatly denied the existence of heavy machine guns—Johan Pilestedt has track record of being tongue-in-cheek, though it's not clear whether he accidentally blurted out some Super Earth secrets or fired a knowing wink our direction, here.

Turns out, we are getting not one, but two heavy weapons to help us in our march against the bots: the LAS-99 Quasar Cannon and the MG-101 Heavy Machine Gun (HMG), which are both available in-game right now. 

Both of these heavy-duty weapons should help thin the herd of Super Earth's foes by offering even more anti-armour options—though the LAS-99 Quasar Cannon appears to be geared most towards taking out tanky enemies, as it's shown obliterating Automaton hulks in its preview footage. That should be a very welcome addition, considering the bot's relative lack of popularity among the playerbase.

The HMG costs 6,000 requisitions, while the Quasar Cannon costs 7,500—if you can only afford one, however, I recommend the HMG just for efficiency's sake, since Troost currently has the «Weapons Experimentation» environmental condition. This makes the Quasar Cannon available to everyone contributing to the war effort.

As for the weapons themselves, I hopped in to test them out. Interestingly, the HMG has massive variations in recoil based on whether you're standing or prone—even more than most guns—making it a more defensive weapon than its Quasar Cannon cousin. This tracks with Pilestedt's comments earlier in the week, where he noted that requiring a tripod was «the idea with the HMG» that didn't exist, but now does.

The cannon, meanwhile, takes about five seconds to spin up before unleashing a powerful blast, then initiates a roughly 12 second cooling period—though I was on a cold planet, so it may take longer to recharge elsewhere.

All-in-all, these weapons should complement your Helldivers' arsenal nicely, helping plug the hole left in our hearts by the Railgun's recent
