The Frozen Trail update dropped the biggest late-game activity ARC Raiders has seen yet: the Fallen Emperor, a massive downed Walker you can actually enter. Getting inside requires the Emperor Gateway Conduit key, and the game does not hand it to you easily. Here's exactly how to get the blueprint, farm the three couplers, and craft the key at your Workbench.
The Emperor Gateway Conduit blueprint does not drop from standard loot crates or regular enemies. There are two ways to obtain it: find the blueprint in the new Pendola Pass map, or reach tier 60 of the Frozen Trail Reward Pass to claim the key directly. For most players, grinding the Reward Pass to tier 60 takes time, so hunting the blueprint in-raid is the faster path.
The blueprint drops from Harvester Payloads, which you can only call in during the Redirection map condition on Pendola Pass. Here is the process step by step:

Once you have the blueprint, you need three specific coupler items. All three drop from the same Harvester Payloads you call in during the Redirection map condition, so you are farming the same activity for both the blueprint and the crafting materials.
| Required Material | Quantity | Source |
|---|---|---|
| ARC Insulated Coupler | 1 | Harvester Payload (Redirection condition) |
| ARC Conductive Coupler | 1 | Harvester Payload (Redirection condition) |
| ARC Plated Coupler | 1 | Harvester Payload (Redirection condition) |
The good news: the Emperor Gateway Conduit key only requires a Workbench I to craft. You do not need an upgraded crafting station, which means you can produce the key as soon as you have all three couplers in your stash. If you want to get ahead on your crafting station progression or need more context on what else you can unlock, the ARC Raiders blueprint farming guide covers loot routes and station unlocks worth knowing.

The Fallen Emperor is a dungeon-style activity set inside the body of a massive downed ARC Walker. The rooms are likely procedurally generated, which means the layout shifts between runs. Early community testing confirms the activity is firmly endgame difficulty, so going in underprepared is a quick way to lose your Conduit key and your gear.

Before entering, make sure you have a Grappling Hook or Snap Hook equipped. Some rooms feature large drops and walls you cannot scale without one. Skipping this preparation will leave you stuck or forced to take fall damage that a Powered Descender blueprint would otherwise help manage.
The primary reward for clearing the Fallen Emperor is the new Amplification Modules rarity tier. These modules significantly change how specific guns function, making them a meaningful upgrade for endgame loadouts. Critically, they fit in a safe pocket, so if you die inside the dungeon, your Augment's safe pocket slots can protect the modules you earned. Plan your pocket layout before entering.
