Creative Mobile, the creators of racing game Nitro Nation, have released a sizable update for the game. For starters, there’s a new mechanic who can both create and upgrade blueprints. Upgrades now are done instantly, and at no cost. Repairs for blown engines are also instant, but continue to cost. And both of those no longer require a mechanic. Cars can also be traded in for one of the following three: cash, a booster package that’s random, or an upgrade kit for cars that are racing class.
