Welcome to Helios

You'll start on the floor, and a Claptrap unit will wake you up, handing you your ECHO device. Follow it to a door it needs to open.

As you enter the next room, you'll encounter enemies. They'll appear as red spots on your mini-map. Don't forget to loot all the containers marked with a green light – this helps with Challenges and replenishes your low starting ammo.

After defeating the first group, more enemies will appear on the right side of the room. Clear them out, then proceed to the next door where the Claptrap is waiting.

The Claptrap will open the door but be killed by a few enemies. Quickly take them out and move into the room beyond to trigger a short cutscene introducing Jack.

Jack will then be ambushed by Lost Legion enemies and go down. Your objective is to clear the room. As you approach Jack, a ship will arrive and drop off more enemies. Defeat them all.

Finally, go to Jack's body and press/hold the indicated button to revive him. This action also applies to downed co-op partners. Reviving Jack completes your first mission.
