In level 7, Midas' Palace, you can get the magnums. When you pulled a lever which opens a small garden with gorillas near the pool you started, go to the left side of the gate. Feel the wall by pressing
4 to pull a secret lever. The gate at the left side will appear. Enter it to get the magnums. Note: The magnum kills with half the number of shots than Lara's pistols. You can use them without worrying about the ammunition, as there will be lots of magnum clips to be found during the game. Note: There is a claw trap near the magnums which can kill if you get caught in between.
Hint: Sanctuary Of The Scion: Uzis:
In level 12, Sanctuary Of The Scion,yo u can get the Uzis. When you reach the big sphinx, climb to the top of its head. At the left side of the slots for the ankhs (looking from the back of the sphinx), walk to the tip of the front. Look around in front for something white in the air. Step back, and do a running jump towards it to get the Uzis and a set of Uzi clips.
