The main objective in Final Outpost: Definitive is to build and manage your outpost while defending it against enemy attacks. You will need to gather resources, upgrade your facilities, and strategize your defenses to survive.

To gather resources effectively, focus on upgrading resource-producing buildings first. Assign more workers to these buildings to increase output and regularly explore the surrounding areas for additional resources.

To defend your outpost, build a combination of defensive structures such as turrets and walls. Position them strategically to maximize coverage, and regularly upgrade them to improve their effectiveness against enemy attacks.

Upgrading buildings is essential for advancing in the game. Follow these steps:
1. Tap on the building you wish to upgrade.
2. Review the required resources and time for the upgrade.
3. Ensure you have enough resources to proceed.
4. Confirm the upgrade and wait for it to complete. You can queue multiple upgrades.

Combat requires careful planning. Use reconnaissance to scout enemy positions, choose the right units for the battle, and consider terrain advantages. Manage your resources efficiently, and upgrade your troops to enhance their capabilities.
