In Last War Shelter Heroes, you just have to touch the different elements in the shelter to level them up or make a repair. However, in order to improve the conditions of the place, you need coins and gold that you can only earn by winning the different battles. This is why you'll need to move around the map to the critical areas where your enemies are advancing.
The combats that you come across in Last War Shelter Heroes are carried out automatically. Even though you can't intervene in their development, you can prepare your soldiers for battle. From the main menu, you can equip your troops with weapons, uniforms, and other elements until you've formed a powerful squadron that's ready to face any wave of enemies who dare to move in on your base.
Last War Shelter Heroes lets you take part in a war where only one side can come out victorious. By creating good strategies and equipping your soldiers with the best technical elements, you'll begin to gain ground on your rival and bring peace back to this land that's been consumed by chaos.
