December 31, 1999, on Hollvania, Earth keeps repeating itself which means you can save all of the Hex members before they perish.
But there is quite a bit of grind before you can get the Hex Finale ending but it is worth the trouble in the end. You can get a decent number of rewards in Warframe 1999 for your efforts to save the Hex.
Know that the ending itself will leave you with more questions than answers.
How to Unlock Hex Finale Ending in Warframe 1999
You must achieve Rank 3 – 2-For-1 with The Hex syndicate. This requires accumulating a total of 71,000 syndicate standing.
To increase your rank, you can find syndicate medallions during Hollvania missions, which are marked on your loot radar.
Alternatively, you can complete bounties from the bounty board near the Atomicycle garage, which also grant additional rewards.
For the rank-up process, you will need:
- 85,000 hollers (credits)
- 30 Hollvanian Pitchweave Fragments
- 15 Efervon Samples
- 12 Entrati Obols
- 5 Experimental Arc-Relays
- One of each of the six Hex medallions
To get started you need to reach at least “Liked” status with all members of the Hex. I found that giving gifts they like is a great way in addition to doing quests and bounties for them.
Use the KIM system to interact with them and give gifts via the DIRECTGIFTZ store. Each member can be interacted with once per day (after server reset), and gifts can also be given daily. Successful conversations and gifts increase your Chemistry Rank with each member.
Some effective gifts for each member include:
- Broadsword / Arthur: KineKitchen™ Toaster or Microwave
- Salem / Eleanor: KineBasik™ Hanging Planter
- Belladona / Lettie: KineKitchen™ Coffee Machine
- H16h V0l7463 / Amir: KineMagik!™ Wireless Headphones
- xX GLIMMER Xx / Aoi: KineMagik!™ Wireless Headphones or Speaker System
- Soldja1Shot1kil / Quincy: Kinemantik™ Digital Video Camera
Once you reach the correct relationship status with all Hex members, go to the backrooms of Hollvania and interact with Kalymos. Select the option to “Attempt New Year’s Eve Again?” This will trigger a short mission where you will revisit the events leading up to the finale.
