First off, you may be wondering what’s the Sleeper Simulant… It’s a powerful 290 Exotic Fusion Rifle that goes into your Guardian’s Heavy Weapon slot. I just got mine last night and am enjoying the heck out of it.
Once you complete the The First Firewall quest, you’ll receive the Curious Transceiver.
Decoding the Curious Transceiver
Enter the code sequence as shown in the image. Once you’ve entered the codes correctly you’ll be given a new quest, asking you to speed run Cayde’s Stash in under four minutes.
Next, you will be given the Ikelos Fusion Core for which you will have to complete the following steps:
- Beat the Archive Mission on Venus
- Dismantle a Legendary or Exotic Heavy Weapon
- Warsat event on Earth
- Warsat event on the Moon
- Warsat event on Mars
The Sleeper Stirs
Complete the Fallen S.A.B.E.R. Strike on Earth on Hard (Light Level 280). Be sure to activate a Three of Coins (you can get these from Xur). On completion, you will pick up the Sleeper Simulant Weapon Frame.
Head back to Banshee-44 yet again to get the Sleeper Simulant. Now go venture the Universe to upgrade your heavy and have fun.
