Star Citizen 4.3.1 patch summary: what changed

Live since 18 Sept 2025 · build 4.3.1-LIVE.10275505 · updated 11 Nov 2026

In short

  • The MedGel system overhauls ship medical beds — revives now consume a physical resource you must buy, store, and reload yourself.
  • Two new RSI Apollo medical ships arrive alongside NPC dropship reinforcements, AI watch-tower turrets, and on-site mission pick-up.
  • Expect tighter logistics around ship respawns and new defensive threats at outposts — bring MedGel and plan for enemy reinforcements.

What changed

Alpha 4.3.1 "Virtue's Descent" (18 September 2025) is a focused update built around medical gameplay, smarter enemy AI, and the second chapter of the Onyx investigation arc.

New Ships

  • The RSI Apollo Triage (T3 medical) and RSI Apollo Medivac (T1 medical) join the roster as dedicated medical vessels built around the new MedGel system.

MedGel — Medical Respawn Overhaul

  • Ship medical beds now require MedGel, a physical consumable you must purchase, carry, and load into each bed manually.
  • Capacity and respawn range scale by bed tier: T3 holds 200 units (2 revives, 50 km range), T2 holds 400 units (4 revives, 8,000 km range), and T1 holds 600 units (6 revives, near-unlimited range).
  • Healing tier injuries also costs MedGel — if your supply runs out, deaths send you back to your home city instead.
  • MedGel Dispensers have been added to medical facilities for restocking.

Gameplay & Missions

  • Enemy AI now arrives via dropships at mission sites in Pyro rather than appearing out of thin air; destroying watch-tower terminals stops reinforcements from being called.
  • Automated AI auto-turrets (watch towers) now defend outposts and mission locations.
  • Certain contracts can now be accepted on-location rather than only through mobiGlas.
  • The Onyx Part 2 (Virtue's Descent) event continues the Frontier Fighters narrative arc with new puzzles, combat, and story content.

Balance & Fixes

  • Ballistic damage reduction adjusted across all ships; missile explosion radii increased for all sizes S1–S7.
  • Roughly 160 bug and crash fixes, including 31 from the Issue Council, addressing mission progression, AI behavior, facility access, and visual polish.
