This clone does not talk, and is not always there however, later when both of you fight a group of soldiers, there are two of them. As the next area is loading, she will appear next to you. Push her into the corner left of the door, then run in and watch it close behind you. When you are fighting alongside Alyx later in the game, at one point you will encounter a door where she tells you to go on without her, while she heads up to the communications room to unlock doors for you. If done correctly, when the jeep flips you will also flip. When you get the jeep, use turbo towards a wall, then press Y to get out before you hit the wall.

Drop it until it leaves the bottom part of the screen, then pick it back up and throw it as fast as possible. Pick up an item without using the Gravity Gun. Never re-activate enemy turrets that you disable. Note: This is important if you are using turrets to kill the CPs coming from the blue openings.

When there are no enemies around, carefully press Y (or L if you have Gravity Gun) until the turret stands up straight and is activated. Pick it up with your Gravity Gun or use key, and face up while you have the turret and it will re-activate. To re-activate a turret, crouch and face the way the legs are sticking out from the turret. Also, make sure that the object is indestructible, and most importantly, look at the enemy and see if you can kill it with one shot. Note: Make sure there are no more that one enemy while doing this. Then if possible, shoot the barrel at the enemy. When you need to run a long way and you have some objects with you (for example, a non-explosive barrel), if you have the Gravity Gun, use it as cover and run (while facing the enemy) to the other side.
