IDK why I'm responding to this. I must be bored
The only weapons that should have any recoil are the starter ballistic weapons. Reason why is, IRL, the projectiles are propelled by rapidly expanding gasses created by exploding gunpowder. That recoil isn't that significant either since most modern weapons are engineered to mitigate recoil as much as possible and are extremely accurate in well trained/experienced hands. Recoil effecting accuracy only becomes a major issue with prolonged gunfire. Like say having a fully automatic weapon and holding the trigger down until all the bullets are gone - it becomes harder to control where the bullets go since the violently expanding gasses make the gun want to jump around. Xenonauts 2 touches on this with how it handles the light machine guns making them fire a lot of bullets inaccurately (a little too inaccurate if you ask me). This is also one of the reasons why the M-16 was revised from a fully automatic rifle to a 3-round burst IRL.
None of the other weapons would have recoil based on their descriptions. Not even the gauss guns which are kinetic weapons, but whose projectiles are fired by powerful magnets.
Its a facking video game, that's how
just a basic concept of a shotgun: a short range weapon that makes up for poor accuracy by spraying a bunch of projectiles all at once. except the bullets are now lasers and it makes a pew-pew sound when fired
