In Star Wars Force Collection, you can build up an entire fighting force using the characters from the Star Wars mythos, whether they are a famous character who appeared prominently in the original trilogy or appeared in one tiny little scene in the middle of Attack of the Clones. You also have a choice of plenty of vehicles that you can take into battle with you, and these can often be the deciding factor between a won battle and a lost cause.
Your main goal, of course, is to complete one single set of blueprints. The first blueprints that you can complete are the T-16 Skyhopper set. As you progress through the quests, journey into new areas and beat more bosses, you will unlock more and more blueprints that can be turned into vehicles.
Blueprints can be found in one of three ways, one way being to win them in battles against other players. You can also find blueprints in the quest mode. Each world that you quest in will have its own specific set of blueprints for you to find. Finally, the third way to find a blueprint is by receiving gifts from your allies.
Once you complete an entire set of blueprints, a scene will automatically pop-up, and you will be able to start construction on a vehicle. Construction will take about 45 minutes to complete, at which point you will be able to unlock the hangar tab from the menu. Go to the hangar and you will see four different vehicle slots. Every time that you complete a set of blueprints, you will be able to go to the hangar and build a vehicle inside an empty slot.
Each time that you complete a set of blueprints that you have already completed before, you will level up that blueprint. With those leveled up blueprints, you will also be able to build a leveled up version of that same vehicle. Keep earning the same set of blueprints over and over to massively increase the power of the same vehicle.
At some point you will also find yourself wanting to get rid of vehicles in your hangar to make room for new ones. You can sell any vehicle that you want to get rid of, in exchange for credits. The more powerful and the higher-level the vehicle, the more credits that you will earn. It is recommended to sell lower-level versions of duplicate vehicles.
