Hidden Military Base Area
You can find this area in the Toxic Refinery (Episode 1, Level 3). Complete the
first half of the level (before you enter the blue door), then go back to the
starting point. Look inside the pool of radioactive waste and you should see a
platform (if you flipped all the switches in the first half). Walk across the
platform towards the wall it leads to. The wall will open and you will have to
defeat a series of enemies. Explore the secret area more and you should find an
exit door. Enter it and flip the switch (the stats will not appear). You will now
be an area called the Military Base. Note: This area can be very difficult.
