It was built by the UAC to defend mars from any unfriendly capital class ships or spaceborne demons. Gotta remember this isn't the first time humanity has faced demons, the events of doom, Doom 2, doom 3 and doom 64 all happened prior.
@@adambrown6669 What kind of spaceborn demon would require a city sized laser death cannon to kill it? The only demon I can think of that may be able to survive space are cacos and pain elementals, and neither of those are anywhere near big enough to warrant this kind of firepower. This remains one of the biggest mysteries in the whole series for me, like what’s it shooting at? Cthulhu?
@@afungai1649 maybe there's a hell portal pouring out thousands of cacodemons that the bfg is slaughtering, it's also a bfg meaning it's shots would kill anything that passes near the main ball.
There is piece of lore in the game explaining that it was UAC fighting against hell fleet per ongoing power struggle. It even included a picture how could those ships look like.
What's kind of reassuring is that you never see it shoot in the same direction twice. In other words, it always kills what it hits in one shot. Not surprising, considering that it can vaporize at least six quintillion metric tons of rock per shot (I mean, that crater it makes in Mars has to be at least 1% of Mars's volume/mass). Each shot from that thing is probably comparable to the energy a Kardashev-II civilization uses per second.
@@joaoborgesrodriguesalves6554 the direction that disappeared has nothing to do with Mars, though considering the power of the BFG 10k, Half of Mars is probably gone anyway. Half Of Mars… sounds like an interesting album title.
Imagine a gun so f-ing big, there has to be a warning issued to the whole facility each time it fires and a dude sits inside of it to fire himself on the different planet 💀
Us : "Wow cool new weapon!" Id software : "thanks, hope you enjoy ripping and tearing" Us : "So where did the bfg 10k firing at" Id software : "Idk" Us : "....."
