How To Unlock Rex Risk Of Rain 2 Character Unlock Guide

8 August 2026 | 71

Risk of Rain 2 offers an impressive roster of survivors, each bringing a unique mechanical playstyle to the chaotic planetary landscape. Among these characters, the symbiotic plant and robot hybrid known as REX stands out for its self-damaging high-reward combat loop. Unlocking this survivor requires completing a specific environmental quest line that challenges your spatial awareness and careful health management during early stages.

Securing the Fuel Array from the Spawn Pod

The journey to unlock REX begins immediately when your drop pod touches down on the first stage of your run. Before rushing off to fight monsters, walk around to the back panel of your crashed escape vehicle to reveal an interactive panel. Interacting with this broken segment rewards you with a highly volatile equipment item known as the Fuel Array.

This item occupies your primary active equipment slot and introduces a severe tactical hazard for the remainder of your journey. While carrying this component, letting your survivor fall below half of their maximum health pool will trigger an immediate, fatal explosion. Choosing a mobile survivor with native healing abilities can significantly reduce the risk of accidental detonation during intense combat encounters.

Navigating Toward the Abyssal Depths

With the explosive device safely secured in your active equipment slot, your primary goal shifts toward surviving until the fourth stage environmental rotation. You must successfully navigate through standard teleporter events while prioritizing evasive maneuvers over reckless point-blank aggression. Taking advantage of defensive items like armor plates or shields can help keep your health pool comfortably above the danger threshold.

To guarantee that you reach the correct destination, consider visiting the Bazaar Between Time to dream for a specific stage pathway. REX can only be repaired inside the subterranean volcanic biome known as the Abyssal Depths, which populates as an option during the fourth stage split. If your run takes you to alternative environments like Siren Call, you will have to wait for the next map loop to finish the quest.

Locating and Repairing the Broken Robot

Upon arriving in the Abyssal Depths, you must search the upper vertical layout of the cavernous arena to find the target. The deactivated chassis of REX sits nestled high above the floor on a series of suspended rock platforms near the ceiling structures. Utilizing geysers scattered across the low ground provides the necessary vertical momentum to reach these hidden upper ledges safely.

Once you locate the plant-covered mechanical shell, approach the interactive prompt to insert your active battery array. Completing this final step immediately triggers the Power Plant challenge achievement and adds the survivor to your character select screen. Players can now enjoy a fresh combat dynamic focused on balancing health consumption with powerful crowd-control capabilities.
