Thaelite Mines

Thaelite Mines is the second level of Unit 1 of Ground Zero. In this level your objective is simple, gain access to the Tectonic Stabilizer; a giant machine which the Strogg are using to combat disruptive natural geological processes like continental drift, earthquakes etc. Proceed through caves, mine halls and the whole facility to get to the security room where the Tank Commander is guarding a Security Pass. Eliminate the commander and collect security pass, which will enable you to open the gate to the Tectonic Stabilizer.

Secrets:

 * #1) In the second room (with the stationary mine cart and red walls), press the button to activate the lift on the ground floor. While you are going down, the left and right walls will explode, revealing two Flyers each. One side has a crack on the wall. Shoot it to reveal a Megahealth.
 * #2) From the lift where Secret #1 was, take the left path at the intersection where the big doors are, go up the elevator and take the right turn; you will come to a dead end with a door that has been dented and not functioning; just across from the door, you will see a piece of Thaelite sticking out of the wall. Shoot it to blow up the wall, revealing an Enforcer and an Ammo Pack.

 * #4) Inside the room with the Tank Commander, Security Pass and other enemies looking to ambush you, you will see a column on either side of you from where you entered; go behind the left column and look up to find a Shootable Button. Shoot it to reveal a wall compartment containing a Silencer and four Stimpacks.
