Simon either ends up where he entered or at the exit along the intended path. The tunnel network here is safe to explore, but doesn't seem to have anything to interest or any alternative exits.Turn right from the flickering blue light and follow the smaller green lights into a tunnel and continue through until reaching an intersection.Sprint if needed to keep up, but stay a few steps away. Select "Control" and then "Tau", and then follow the robot to a flickering blue light.Turn left and go to the console outside the garage.Optionally listen to the data buffer on the intercom to the left and use the healing node.Go inside through the open doorway where the door has fallen off its hinges.To avoid taking hits, just sprint along this path the moment the first blue light is reached until the exterior of the next building is reached.There will then be more blue lights before a building is reached. After this, there will be a large gap where dimmer green lights will be instead. Out the door in the distance, there is an another group of blue lights.Even waiting for the signs of their presence, the static sounds and visual distortion, will likely mean Simon takes a few hits when sprinting away as they swim faster than he can run. The optimal evasion strategy seems to be simply sprinting through their patrol area. Stealth appears to be useless as a way to avoid them, as is staying near the lights. Once he has been knocked out, though, each subsequent hit will knock him out again and eventually kill him. It takes many hits from them to knock Simon out. Warning: Up ahead, there is an extremely hostile school of fish with extremely large teeth. Exit through the door to the right of the console.Note that the switch here will break and shut off the lights inside. Optionally check out the console and use the healing node behind it.Continue to the next sign reading "525m".Upon reaching an area with round red lights to the right of the blue lights, the new monster will emerge briefly from the left, but will turn away quickly even if Simon sprints up to it.Continue into the abyss between the blue lights.This can be done several times without Simon dying. In this case, Simon will be brought back to the path and will awaken there. It attacks only if Simon Jarrett goes too far off the intended path. Note: There is a new monster ahead: some kind of very large fish. The blue side indicates the heading to Tau while the red sign indicates the heading back to the climber. As per the sign above the switch, the lights serve as a directional indicator.This isn't required, but it's easier to accidentally stray from the path without the lights. Pull the switch here to activate the lights along the path.Continue ahead to a green-lit sign saying "700m".The white light in the distance ahead is the monster pictured belowĪ slow moving monstrous fish with a white light This robot serves as a guide through a dark stretch of the path Optionally visit the building to the right to view a map to Tau.Ī creature encountered on the path to Tau.The lever next to the door on the right will activate lights in the area, so flip it.Continue ahead to the next pair of buildings.Optionally go through the door with a yellow light overhead for an intercom with a data buffer.Optionally go inside the room with a green light over the door to investigate the terminal.Leave the climber, go down the stairs to the right, and turn left.Swipe the omnitool where indicated and open the grate.At the bottom, stand up and retrieve the omnitool.
