LEGEND (Map EP1):
1. Dig site
3. Train station
Before going further, enter the squad data and spend talent points. You can also take a while to get to know controls. Then go along the path.
Hint! It's good to spend first points on charm/intimidate. They will be helpful while completing quests on Eden Prime.
Soon Jenkins will be killed by geths. Eliminate them and examine Jenkins body. Continue north. You will meet Ashley who will join your squad. Continue further along the path.
You will see how geths treat captured humans. Kill the enemies and enter the dig site (EP1-1), then clear the area. It seems that the beacon you were looking for was moved away. Go northeast to the research camp (EP1-2).
After a short fight decrypt lock to the nearest cargo bin. Enter it and speak with the survivors. It looks like you need to go north to the train station. Kill all enemies there and break into cargo bin situated nearby.
You'll meet three farmers inside. While talking to a man named Cole you'll be able to use your persuasion talent (charm/intimidate) for the first time. This way you'll learn about weapons-smuggling ring and hear the name of man who was their contact at the spaceport. Receiving this information will gain you experience and morality points.
Enter the train station then and examine the turian body. Soon you'll meet Powell who managed to survive the attack. Talk with him to find out what happened.
Hint! If you talked with Cole about Powell before, you can now question him about his connection with the smugglers. It will let you use your charm/intimidation talent again and gain more experience and morality points (and a little material bonus as well).
Now you just need to get to the train station control panel (EP1-3). There's a lot of covers along the way so you shouldn't have much problem with eliminating all enemies. Activate the train controls.
LEGEND (Map EP2):
1. Final train station, demolition charge
2. Demolition charge
3. Demolition charge
4. Prothean beacon
You have few minutes to eliminate geths and disarm four demolition charges. First disarm the nearest charge (EP2-1), kill enemies at the end of the walkway and then disarm the rest.
Turn behind the building and shoot down at the enemies. After clearing the area, search all containers and boxes to take the equipment. Then examine the prothean beacon (EP2-4).
You'll wake up on the board of Normandy. Talk with doctor Chakwas and captain Anderson and leave the medical bay. You can chat with Ashley along the way. Go upstairs on the higher level and enter the bridge to talk with Joker.
