History of Lossless Compression

Revision 25172 by archivist at 2026-10-10 09:22:35

Lossless Compression is a Triumph in Destiny 2 from Season of the Splicer. It requires completing Expunge missions without dying. It sits with the other Expunge triumphs, including Quick Hack, Unpredictable (Expunge: Delphi without dying) and True Variable (Expunge: Delphi solo without dying).

Finish the weekly Path of the Splicer quest from Mithrax in the H.E.L.M. This unlocks Expunge.
Pick a variant and start it from its location: Labyrinth from the Tangled Shore, Styx from the Moon, and Tartarus or Delphi from Europa. Delphi is the final variant.
Complete the mission without dying. The triumph does not single out a variant, so any Expunge run with no deaths counts.

Learn the opening section first. It is the same in every variant.
In Delphi, use the Wirewalker shortcut if you have it unlocked.
In Styx, recharge Authentication Keys on the small white cubes to extend their timer.
In Tartarus, stand in the center pool to gain the security buff, which lasts up to 32 seconds.
In Labyrinth, the boss Fantis is about as strong as a Lost Sector boss, so Supers and Power weapons work well.
In Delphi, the boss Quria has a wall attack. Heavy weapons or your Super help end the fight quickly.

Each Expunge boss gives a reward. In Delphi, these are claimed from a Corrupted Chest.
