From this page of the guide to Outriders, you will learn how to quickly gain experience points (XP).
Experience points in Outriders are necessary to level up your character, thus increasing your stats, unlocking additional class skills and gaining class points that can be used to develop the skill trees of each subclass.
Experience points in Outriders can be earned in two main ways: by completing story quests and side missions, and by eliminating enemies. It should be noted here that the World Tier doesn't really affect the amount of experience points you earn, but it does have a big impact on the quality of the acquired rewards.
Choose a World Tier that allows you to quickly clear an arena besieged by a many of enemies without having to constantly take cover.
Playing at the highest possible World Tier will cause your enemies to be more resilient throughout the game, and as a result, you will have to be very careful at all times and not expose yourself to attack, which will effectively slow down your progress.
Farming XP in Outriders boils down to finding a plot point with a an enemy-dense area and repeating that action. The following gameplay stages are worth noting:
- Trench Town: a plot point Push back the Insurgents in No Man's Land;
- Quarry: a plot point Cross the swamps;
- Forest Enclave: a Predator to Prey side quest where you have to fight your way through a jungle full of monsters and at the end fight the mini boss Tyrannus.
