My idea is, that gadgets are something like implants but for mechs/weapons, each wepon/mech has its own few Gadgets you can choose one from them and use like 3 times a battle for example, that the next 4 seconds the minigun shoots a lot faster or, that the next shot of the disc launcher does a bigger explosion radius or, that MD make teammates in it's radius faster for a certain time instead of healing them. I would put much more variety in the game because everyone can have a slightly different mech and not just the same killshot with javelins.
