TL;DR
Warframe Update 12.1.0 added the Grinlok to Clan Tech and the Market, introduced several HUD/UI changes, and fixed a range of bugs affecting mods, abilities, and mission behavior.
What Changed
- Added the Grinlok as a new Tenno Reinforcement, available in Clan Tech or the Market.
- Added a HUD/UI tab to the Settings menu.
- Added a “Show Ability Dots” option in Settings.
- Updated HUD elements and scaling fixes for the reload timer and sniper reticles.
- Changed Survival objective markers to a new icon.
- Added colorized minimap icons for Interception based on faction possession.
- Reverted holster changes back to their original positions from before Update 12.
- Clarified the polarization screen description.
- Interception now gives XP for capturing, neutralizing, and dominating.
- Fixed nightmare-mode rewards on Interception missions.
- Fixed Ranked Mods not being tradeable.
- Fixed several ability and mission issues, including:
- Nova’s Wormhole having infinite range.
- Banshee’s Sonar not showing enemies on clients.
- Heavy Impact only playing once.
- A Nekros-summoned ally being able to squad up with enemy AI and take points in Interception.
- Keys not being used in inventories if the host leaves or an election occurs.
- Vauban’s Tesla not being destroyed between Conclave matches.
- A trade/contribution screen overlap issue.
- A tint color mismatch with Ember Prime.
- The Harvester ignoring players after a death/revive timing issue.
- The update also included a mod inventory rollback script for affected players, covering missing mods and certain overfusion, selling, and trading cases.
Player Impact
The biggest gameplay-facing changes are the Grinlok’s addition, the new HUD and settings options, and the Interception updates. Players running Interception should notice clearer faction control on the minimap and XP being awarded for capture-related actions. Several bug fixes also affect core play, especially Nova, Banshee, Nekros, and mod trading.
If you were affected by the missing-mod issue, the update notes say a script was being deployed to restore entitled mods and handle related inventory rollbacks. The notes also state that players who had already spent ill-gotten credits or platinum would be set to zero rather than allowed to go negative.
