There are 4 Memory Shards, 1 Audiolog, and 2 Artifacts. 1. Memory Shard: First encounter where you need to break to the right not to get hit by the enemy on the other side. Once inside, look to the right, where there's the usual wall to break, and continue the path to find it.   2. Memory Shard: On the tight corridor, after crossing the first wave of enemies and opening the door, just after reaching the second door, look left. Please do not cross the door, as it will close once you do.   3. Audiolog Threat: The first wall where you must throw the shuriken to wall run is next to an air vent. Use the air vent to change direction on the wall above the vent, as you need to do so to grab the Audiolog.    4. Memory Shard: In the area where a big red publicity screen is, jump to the first wall by throwing a shuriken and then to the pole. Throw another one to the wall on the right, go under the wall on the left, throw once more to the last on the right, but this time pull yourself and don't run, fall under the wall on the edge, and then once again throw a shuriken to the one above the square with stripes drawing.   5. Artifact Holotat: Before crossing the door, go down and turn right toward the red door. The artifact Artifacte left of the red door.    6. Artifact EMP Grenade: In the same area as the previous Artifact, Artifact and look for the wall behind you and throw a shuriken to open the door. Once you hit it, go to the door in front. If you're next to the switch, the door is on the graffiti wall.
