Unit 8 

U8L1W1 Strategy

While staying under the cave ceiling for protection, kill the Icaruses one on one instead of making yourself vulnerable all at once. 

U8L1W2 Secret

The cave on the lower right has a cracked wall behind the lava. Shoot at it to uncover a secret area with a power shield.

U8L1W4 Strategy

In order to get across the bridge, you must climb up the side of the mountain and walk around to the plate on the floor. This will unlock the gate on the other side.

U8L1W5 Secret

Before you go across the bridge, hp back up the side of the mountain again and press the green button directly over the door where you first came out. This will open up a secret area on the inside of the cave so drop back and head back in for some power-ups.

U8L1W7 Secret

After killing the Strogg on the other side of the bridge, go back out the way you came and climb around the mountain for the third and last time. Jump up over the door where you came in and enter the now-opened cave with a health pack in it.

U8L1W13 Secret

Near where you grabbed the data spinner is a wall that opens when you shoot at it. Then step on the plate on the floor, turn around and press the green button. This extends the bridge outside this room.

U8L2W1 Secret

Shoot the Strogg and enter the small square to their lower left. This leads you to a few sets of stairs and some power-ups.

U8L2W2 Strategy

When you open the door on the middle level, stay inside and fight the mob from where you are. If you walk out into the hallway, you’ll get hit from all sides…

U8L2W4 Secret

To get that quad damage on top of the blue structure, shoot the face behind it and the one on the opposite wall and it’ll drop to your feet.

U8L2W10 Secret

Shoot the outline of a rectangle on the wall to disable the laser trap.

U8L2W12 Secret

Near where the laser traps starts, shoot the yellow computer and it’ll open up. Jump down and collect the power-ups.

U8L2W14 Secret

In the room that disables the green force-fields, press the wall, then walk outside to collect your mega-health.

U8L3W2 Secret

Through the right door with the red force-fields, look up at the ceiling and shoo the button to open up a compartment in the wall.

U8L3W3 Secret

Drop down behind where the laser trap is and quickly jump out of the lava onto the small compartment underneath for some goodies. Take the small platform back up to the surface.

U8L3W6 Secret

Drop down into the small room with the yellow force-fields. In a moment, a Technician will break through the ceiling. Killing him releases some ammo down onto you.

U8L3W9 Secret

On the top floor of the narrow platform shaft, there is a panel in the wall to shoot. This opens up an area to some invulnerability.

U8L3W10 Secret #1

Drop down into that small room with the yellow-force fields. Now that they’re de-activated, make your way to a small cove with a brick wall. Shoot the center of the wall to get at the body armor.

U8L3W10 Secret #2

While in the small room with the brick wall, press the ledge in the corner of the toxic pool and the bottom will drop out. You can now swim to a secret shrine honoring id software programmer John Carmack.

U8L3W11 Secret

Drop down into the dark corner off the main bridge and pick up the pile of power-ups.

U8L2W20 Secret

Return to the room you started in and crawl back into the opening with all the ladders. You can now access the power-up closet full of goodies since the yellow force-fields have been de-activated.

U8L1W15 Secret

Any time after de-activating the red force-fields, you can return back to Level 1 and snag the power-ups in the above-ground opening between the pipes.
