Prototypes
I think it would be cool if you could add a system where if you have purchased a mech, and you use him in your hangar, you would start getting red prototype blueprints for him depending on how leveled up it is. Ex: 1star: 1% 2star 3% etc. If the player accumulated enough of these blueprint it would give them an option to turn their mech a prototype version, which is like the old mech but slightly better and different. The process would take a long period of time and prototype blueprints. You would not be able to purchase proto blueprints because it would ruin the whole idea. I would like to welcome prototype version ideas for mechs and weapons below \/
