After you finish “Know Your Enemy,” you’ll get an email about kett ships firing on each other as they crashed to Elaaden. The end of this mission will give you a chance to exploit the eponymous dissension in the ranks of the kett for your benefit — weakening the kett forces during the game’s final battle.
- Check your email.
- Investigate the crashed kett ships on Elaaden. Head to Elaaden and follow the map marker to the crash site.
- Defeat the kett. There are a few chosen and wraiths that survived the crash. Fix that.
- Search the site. You’re looking for another datapad among the wreckage. You’ll get the “waypoint nearby” beeping on your HUD. If you don’t, poke around in the rocks nearby to make sure there aren’t any kett stuck. Shoot them if you find any, then head back to the crash.
- Speak with Suvi on the Tempest. She’s up front where she always is. She’s got a plan, but she needs Lexi’s help.
- Confer with Lexi. Lexi and Suvi need to use the samples you picked up during “Know Your Enemy” to unlock the datapad.
- Locate the source of the signal on Eos. The datapad points you to a transmitter on Eos. It’s just north of Podromos. It’s a little confusing because the signal is in a cave, so the marker is a little misleading. The cave you’re looking for is right up the hill from Podromos.
- Scan the relay to track down source of signal. Follow your HUD to the relay. It’ll send you on a hunt across the surface of Eos.
- The next two steps (and the beginning of the third) are mostly the same. There are more — and more difficult — kett at each, but the process is the same.
- Track the signal to the second relay. Drive to the marker, shoot the kett, turn off or destroy the shield generator, then scan the relay.
- Track the signal to the third relay. Drive to the marker, shoot the kett, turn off or destroy the shield generator, then scan the relay.
- Track the signal to the fourth relay. Drive to the marker, shoot the kett. There’s a lot of them this time, but there’s no shield or relay.
- Investigate the building. There’s lots to scan and an audio log to listen to, but your ultimate goal is the console in the back right corner.
- At the console, you’ll talk to Primus, who works for the Archon, but doesn’t support his policies. Primus will offer you a deal that effects the end of the game — a kill-code that will lower the defenses on one of the kett ships.
- If you take the deal, the kett forces will be diminished during the final battle. If you refuse, they won’t. That’s the choice you’re making. And there’s no downside — in this installation of Mass Effect. We don’t know any more than you do here, but it sure feels like the kind of decision that will come back to bite you later. But that’s just a guess.
