a test maze chamber

lowerest level is a maze which at times is poorly lit
the next level you have 2 chooses
A the death room where you have little chance of surviual aginst the turrets
B jump the pool of deadly acid
then
A you ride on light tunnels to the top
B you ride lifts to the top

then just have to jump down a hole and do a portal jump to get to the button that will move some sheilds around to keep you safe but don't linger because if you do you will lose the protection from turrets

good luck, you'll need it
