Arena: Breach Executable

Overview

Arena: Breach Executable is a three-player seasonal Arena activity from Episode: Echoes, set in Arcadian Valley on Nessus. It is launched from the H.E.L.M. after completing the Echoes introductory quest and speaking with Failsafe. The Standard version is matchmade at 1945 Power with rotating modifiers; see Arena: Breach Executable (Expert) and the private Expert version for harder versions.

Encounters and mechanics

Players kill enemies to collect data motes (up to 10 at a time) and deposit them at marked pylons, then complete rotating tasks such as capturing points on Vex milk pools (Install Analytic Sequencer) or using a Minotaur's weapon to destroy floating nodes (Redirect Vex Signal). A hidden Planetary Assimilation Piston side objective between encounters grants bonus loot, and Crimson Radiolaria can be collected for extra seasonal rewards. The final boss is randomly one of six: Aulete, Kitharodes or Rhapsoidos (Choral Minds), Polysis (Nessian Gatelord), Tym (Guardian Slayer) or Vire (Shard of Contempt). Bosses are highly resistant to non-precision damage, so precision and linear-fusion weapons are recommended.

Rewards

Echoes-themed weapons and armor (including the Untethered Edge armor set), progress on the episode quest chain, and unlocking Failsafe as a vendor. Gear can also be focused at the H.E.L.M.. Sources describe weapons of several damage types; exact drop pools may have changed since release.
