Missions

Introduction
Going through the story should be your main priority as it is one of the more convenient methods of both leveling up and gaining some Mito. Driving around the different cities will also help with unlocking some of the coupons that you'll need to be able to drive your favorite cars. However, after some time missions will have a level cap that a player needs to meet before they can continue with the story. My advice here would be to do the Call Sign HUV missions that you receive after almost every mission completion. This will help keep you above the level cap for a while and extend your playtime before a level cap is reached. Another issue players might run into is some missions being a bit too difficult. My advice here would be to not use the (N)ormal Mittron Enhancers you receive during missions and save those for when you are able to purchase a couple of sets from the available parts in the Parts Shop and then enhancing those. At some point in the story, you will be asked to join one of two parties: OMD and ROO. OMD playthrough will keep your access to Call Signs and reward you with a little more mito, while the ROO playthrough will reward you with more EXP at the cost of losing your Call Signs. As it is now, you cannot use a HUV Call Unit item to get HUV missions as ROO.

Navigation Arrow
While the navigation arrow might show you the shortest path to your mission location, it may not be the fastest. If you are failing a mission double check the route on the map before you start.

Timer
Mission timer does not start ticking until you leave the starting position. You can wait on the spot for your boost bar to fill up or maneuver around to get a better starting angle.

Level Requirement
Some missions have level requirement. Once you hit the level requirement you might have to do a little bit of other daily activities to get to the required level.
