• Buildings are the foundation of your adventure. Higher-level buildings give you access to more resources, stronger soldiers and more advanced technology.
• You can tap a building and then tap Details to view its function.
• Tips: before you fully understand the functions and importance of all types of buildings, you'd better construct and upgrade them evenly.
  

• Resources support your construction and warfare. Constructing and upgrading buildings, training soldiers and researching technology all require resources.
• You can build various types of resource buildings. Resources accumulate in these buildings over time. A bubble will appear when the resources are ready to be collected. You can tap the bubble to collect the resources.
• Tips: Don't forget to collect your resources as often as possible! After a resource building is full, it will stop producing resources.
  

Train Soldiers

• You can train different types of soldiers in troop training buildings.
• Soldiers consume Plastic. The large your army scale, the higher its upkeep and therefore higher consumption of Plastic.

Research Technology

• Technology provides bonuses to your adventure in economic development as well as on the battlefield.
  
• Technology is researched in the Lab. The higher your Lab level, the more technologies you can research.
