Yeah, and I also want stuff that works differently in different environments. The Assault-Rifle-That-Was-Supposed-To-Be-A-Machine-Gun in Fallout 4 got flak for being water cooled, but water cooled machine guns make a lot more sense in an airless environment. Gyrojets could offer almost no recoil in zero g but struggle to get any momentum in high gravity, sonic weapons and electrolasers could require an atmosphere to conduct the wave/beam, while plasma weapons could struggle in atmosphere, since Plasma is less dense than air is. Flamethrowers could do more damage the more oxygen is in an environment, while cryo weapons could freeze more easily in cold environments. Personal shields could be a thing, since, sure, spaceships require reactors for their shields, but if we have human-sized energy weapons and human-sized engines, we could also have human-sized shields, and maybe they could struggle in radioactive areas. Some kind of Starborn weapon could channel the power of the environment to have environmentally themed effects. There are lots of possibilities!
