[Doom Eternal] why is the Ballista the only weapon that sends Doom Guy backwards when he fires it in the air?

Surely the super shotgun or the rocket launcher have a pretty big kick too but they don’t push him back at all.

Bonus: how does the chainsaw refill itself?

Especially in Doom Eternal, a lot of the weapons have some sort of supernatural bent to them.

The physics involved in the Doom Universe don’t really conform to our own. Doom guy can manifest weapons out of thin air, refill his ammo and health by sucking the lifeblood out of his slain enemies (not just an in-game mechanic, it’s also imploded by lore)
