Like the other games in the franchise, Halo Infinite's campaign offers a few different levels of difficulty; easy, normal, heroic, and legendary. Completing the campaign on legendary is a complicated task, one which becomes even more challenging when players equip all 12 skulls available in Halo Infinite. The reward for completing the game in legendary with all skulls on (LASO) is the rare achievement, "Headmaster," a coveted prize.

Unlike other Halo games, Halo Infinite's epic campaign is missing a co-op mode. This means that players will have to face the challenge of acquiring the Headmaster achievement alone. To do that, there are some tips and tricks that all players should keep in mind. Completing Halo Infinite in LASO means being aware of everything the gameplay has to offer, as well as being willing to spend a long time learning about the details of Infinite's campaign.

How to Complete Halo Infinite in LASO

Halo Infinite Players Want a Weather System

There are many dangerous foes in Halo Infinite that can spell doom for players no matter what difficulty they play on. These enemies become even more deadly in LASO. In order to defeat them, players need to keep a few things in mind. The first is this; not all enemies need to be defeated. Sometimes, it is better to sneak past foes or find different routes to objects. Indeed, players now have more freedom than ever to choose their own paths thanks to the grappleshot. Another thing to keep in mind is that taking out long range and high-health enemies should be the first priority. Charging into fights without killing them first is a mistake in Halo Infinite that players can't afford in LASO.

It is also important for players to remember that plasma damage does more damage to shields, while bullets do more damage to bodies and armor. For that reason, players should consider carrying one plasma weapon and one regular weapon at all times. The plasma can be used to drain shields, and the bullets can be used to kill enemies once they are vulnerable. It's also worth remembering that the grappleshot makes Halo Infinite's melee combat smoother and more effective. Players should take advantage of melee opportunities to finish low-health enemies.

Acquiring the Headmaster achievement is not an easy task, but by keeping the basics of Infinite in mind, players are able to navigate their way through the campaign. Using powerful new Halo Infinite weapons like the Skewer to finish strong foes is important. The previous tips are essential as well. By picking the right fights, targeting dangerous enemies first, and using the proper loadouts, players should be able to finish the campaign in LASO.

Halo Infinite's campaign is not easy. 343 Industries has assembled a roster of bosses that will challenge even seasoned Halo fans. Playing through the campaign in LASO, alone, will be even more difficult than most players expect, but that doesn't mean it's impossible. With some creativity, patience, and dedication, players can get the Headmaster achievement in short order.

Halo Infinite is available now on PC, Xbox One, and Xbox Series X/S.
