In Epic War 4, green upgrades are unlocked by earning experience points (XP) through battles. As you defeat enemies and complete levels, you accumulate XP, which contributes to your overall level progression. Once you reach certain level thresholds, new green upgrades become available for purchase in the upgrade menu. Focus on completing missions and defeating tougher foes to maximize your XP gain and unlock these enhancements.
