This idea, I love it! I'm thinking that you can purchase the satellites in a store on an asteroïde or on a planet or having a crafting statton in your ship. I agree also for the pods launched in planets in order to examinate the planet
Illumination: Seems pretty meh. There's a lightdrone mod that functions in a much better way than this. Scanner: Given that monsters appearing tends to be random, creature count wouldn't necessarily work. Laser: I could see that being useful, although I think some debate would be needed on damaging layers, particularly when it comes to griefing in multiplayer. Maybe if it was limited to boss fights. Power: Why not have it boost your energy bar instead? Antigravity: Not sure what this would add to benefit gameplay other than a simple gimmick. Electromagnetic: Given current features, this one seems useless. Matter Mod: Essentially a god mode type of deal and shouldn't be added. Makes it way too easy. Weather: Could be useful. Orbital: No different than laser. I'd say choose one.. Accelerator: Buff satellite could be neat.
