📋 About This Mod
Collectors Return
Collectors have emerged from dark space on low-velocity spacecraft to support the Reapers. They have been using Collectors as deadly reserves to wipe out resistance in conquered territories, but now the Reapers are directing them to hunt down their creators - the Leviathans.
The Collectors appeared to die out in Mass Effect 2, but Mass Effect 3 Multiplayer they made a surprise return, along with new lore that explained where they came from. Additionally, there are small clues in Leviathan DLC itself that suggests they were due to appear.
This mod takes the ME3MP Collectors and brings them into Leviathan DLC. They make up a blended faction of Collectors supported by certain Reaper enemy archetypes such as Brutes.
Canon Renaming
Collector Troopers and Collector Captains feel like they were named to suit multiplayer mode, so we have taken some names from Mass Effect 2 Collector enemy archetypes to make them feel more tied to that game.
Collector Troopers are now Collector Drones
Collector Captains are now Collector Guardians
Codex
A new codex entry has been written to explain the return of the Collectors using Mass Effect multiplayer lore.
FAQ:
Is this mod compatible with X?
Hard to say. The mod will be compatible with all of Expanded Galaxy Mod and LE3 Diversification Project, as well as any and all of my other mods. Any others are on a case-by-case basis, but it should be noted that few mods edit these missions.
Why are there Reaper enemies with the Collectors?
This is due to some full motion videos depicting Reaper enemies in certain missions. To keep the mod feeling immersive, I have let a small number of Reapers fight alongside the Collectors. This means that you're fighting hybrid factions in these maps, but ultimately they're both serving the Reapers.

✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved with 328 endorsements and over 11k downloads—clearly a hit with players.
- Fresh take on the Leviathan DLC, mixing Collectors with Reapers to keep combat unpredictable.
- Lightweight overhaul that changes enemy composition without touching other game systems.
⚠️ Cons
- Last updated in December 2024—might not be compatible with the latest game patches or mods.
- Only affects the Leviathan DLC, so if you're looking for broader enemy variety, this won't help.
For Mass Effect 3 veterans who've played the Leviathan DLC multiple times and want a new combat twist. Also for players who enjoy fighting Collectors and want to see them integrated into the DLC's story. Skip if you prefer the original Reaper-only encounters or want a mod that changes more than just enemy composition.
💡 Beginner Tips
- Make sure to back up your original DLC files before installing, in case you want to revert.
- Check if you have other mods that alter Leviathan enemy spawns—they might conflict.
