Your Jackal fighter jet can be upgraded and customized between missions on the Retribution's hangar deck. These upgrades enhance its combat capabilities, making space battles more manageable. Available upgrades include improved armor, stronger weapons (e.g., more powerful machine guns, advanced missiles), and enhanced countermeasures (e.g., more effective flares). You earn 'Salvage' and 'Upgrade Kits' from completing missions and side activities, which are used to purchase these enhancements.
Prioritize upgrades based on your performance in space combat. If you find yourself taking too much damage, invest in armor. If you struggle to take down enemy fighters quickly, upgrade your weapons. Some upgrades also unlock new special abilities for the Jackal, such as a temporary speed boost or a more powerful area-of-effect attack. Experiment with different weapon configurations to find what suits your dogfighting style. A well-upgraded Jackal can turn the tide of any space battle.
