To build a base, the player must acquire basic components such as floors, doors and windows, which are acquired gradually as the player progresses and collects levels.

Players can also craft props in the game, such as weapons, which can be achieved by collecting the resources and skills needed to craft them. In addition, players can craft add-ons and add them to weapons, such as adding a scope or flashlight to a pistol or machine gun.
