I wish I could say that with its latest update, GTA Online has jumped the shark, but it already has guns like the Up-n-Atomizer. Perhaps it's jumping another shark of at least equal size. Anyway look, you can now buy your very own portable laser cannons, as seen in the in-game cartoon show Republican Space Rangers.
Yesterday's update adds the Unholy Hellbringer and Widowmaker to the inventory at your local Ammu-Nation. The former has a rifle-like frame with a drum mag and costs $449,000, while the latter is carried underarm like a minigun, has a maxed-out fire rate, and costs $499,000. A variety of garish skins are available for both, with prices starting at $5,250.
These prices put them among the most expensive personal weapons in the game. One big advantage they have – as you can see in the gameplay video below courtesy of GTA Series – is that they each have a magazine size of 9,999, so you don't need to worry about reloading them until all your rounds are spent.
