Unlocking the All Allies Joined trophy in Horizon Zero Dawn requires Aloy to rally key companions before the final battle at Meridian. Gathering these brave warriors not only satisfies trophy requirements but also provides tactical support during the ultimate siege. By completing specific side quests throughout the world, players can guarantee that every potential defender stands ready to protect the city.

Key Questlines to Complete Before the Final Battle

To recruit all available allies, players must actively complete optional questlines across different regions. Essential missions include helping Talahnah in the Hunters' Lodge storyline and resolving the political conflicts involving Vaanas and Urid. Completing these story arcs builds strong alliances and ensures key figures show up when Meridian comes under attack.

Additionally, assisting characters like Petra in Free Heap and Janeida in Sunfall secures critical support for the defense. Each completed side quest directly impacts who will arrive to assist Aloy during the game's climax. Ensuring all these objectives are met before initiating the point of no return is necessary for full completion.

Unlocking Essential Allies in Meridian and Beyond

Certain key companions require specific dialogue choices or mission resolutions to join the final defense. Characters such as Nakoa, Sona, and Teb become vital assets once their individual personal struggles are solved through Aloy's intervention. Ensuring their safety and freedom allows them to travel to the capital to prepare for battle.

Furthermore, completing the quests related to Elida and Aluki guarantees their presence on the battlefield. Each ally brings unique dialogue and battle assistance during the defense of the Ridge and the Spire. Taking the time to finish these secondary tasks enriches the overall narrative experience immensely.

Managing Dialogue Choices and Missable Content

A common concern among players is whether specific dialogue choices can permanently prevent allies from joining. Fortunately, Horizon Zero Dawn is forgiving, meaning dialogue options do not locked characters out of the final confrontation. As long as the corresponding side quests are finished, the allies will automatically appear in Meridian.

Players should double-check their completed quest log before resting at Olin's apartment or proceeding with the main mission. Checking both the Ridge and the Spire defense sites allows players to visually confirm the presence of their recruits. This careful verification step ensures no required companion was inadvertently left behind.

Preparing for the Ultimate Siege at Meridian

Once all side quests are fulfilled, Aloy can initiate the final quest chain with complete confidence. Visiting both defensive positions before resting gives players a chance to interact with every recruited ally. These conversations offer deeper narrative context and demonstrate the true impact of Aloy's journey across the post-apocalyptic world.

Having a full roster of defenders makes the intense combat encounters during the final mission much more manageable. Their assistance on the battlefield provides vital distraction against incoming heavy machines. Achieving full recruitment ultimately rewards players with the coveted trophy and a satisfying conclusion to the campaign.
