Sparrow and ship upgrades After buying a sparrow you will have three upgrade slots on a sparrow and I can glue on these upgrades One upgrade will affect sparrow movement (Extra boost speed, longer and faster lateral movements or the timebreaker upgrade with super speed). Second slot would be a defence/offence upgrade some things would be (increased armour doubling your Durability, guns and a shield which would drain your boost if you want it to regen faster). Third would be a special one such as cloaking There would also be custom paint jobs The prices would be graded in order of worst to best (for example a shield would cost more than durability)
