Don't be jealous of Helldivers 2 getting a hotshot lasgun, because...

It's not the backpack-fed hellgun that you're hoping for. It doesn't unleash a stream of red laser beams, it's the Hotshot MARSKMAN RIFLE from the Kasrkin killteam box. Which means Helldivers 2 got the Darktide Infantry Lasgun and instead of red beams it's yellow bolts.
