Unit 3

U3L1W1 Secret

Look beneath the span you’re on and you’ll see an opening just above the waterline. Jump down and enter, then a platform will take you back up to the surface.

U3L1W3 Secret

Press the green button on the center wall to open up a secret jacket armor to the right. Watch out for the Flyers to emerge first, then hop up on the ledge to collect your prize.

U3L1W5 Strategy

Instead of setting of the laser trip alarms in the large room, head back out the front door and hop into the large pipe on the lower left side. Follow it around to the back of this building and step onto dry land to continue on with the level.  

U3L1W6 Strategy

Follow along the long corridors to a large room with many power-ups littered about. Climb up the ladder and shoot through the grate to gain access to the upper floor.

U3L1W6 Strategy #2

Carefully ping off the Gunner from behind the canon. Use the pillars for protection and keep moving so he can’t aim effectively.

U3L2W1 Strategy

Killing the Tank won’t be an easy task but remember he’s slow…and to use the hallway as protection. Use something powerful against him, and when his shoulder swings around with the rockets, get the hell out of there…

U3L2W3 Strategy

To make it easier later when you return back to this level, climb up an out to kill the Gladiator and Beserker below you near the yellow security lasers.

U3L2W5 Secret

Shoot the glowing yellow light above the stairs where the Gunners was, and quickly drop down into the jail cell area and back out the way you came. If you’re fast enough, there will be combat armor under the stairs. Watch out for the Gladiator!

U3L2W6 Secret

To get in the center room, press the green button at the back of the building, then head back near the prisoner cell area and press that green button as well. Now venture to the side of the room to get in, and down to the goodies.

U3L3W1 Secret

In the doorway to your right as you enter the level, shoot the panel near the yellow laser security doors, and it will open up to a handy grenade launcher.

U3L3W3 Strategy

Tackle all the Strogg in this room one at a time if possible. Use your new-found grenade launcher to bounce grenades off the walls to kill the Gladiator.

U3L3W3 Strategy #2

Look under the stairs for some power-ups, and crawl into the barrel for a quad damage. Beside the barrel are some stimpacks.

U3L2W8 Strategy

There are lots of Strogg to kill in this hallway so use something with a quick load like a machine gun or chain gun. When you get to the top of the platform, turn around because a pack of Flyers will tear out of the wall at you. Jump in to collect some jacket armor. 

U3L3W6 Strategy

To destroy the Tank in the cave area near the yellow lasers, use your grenade launcher and find a good hiding spot behind the wall for cover. You’ll hear when he’s dead.

U3L4W1 Secret

Before heading down the platform, look outside to the right and snag the hyper-blaster weapon and some cells as ammo.

U3L4W2 Strategy

To on a guard rampage in this level, killing everything in your path. Stay on the platform you are on and go around in complete circle. If you’re so inclined, aim at a few below you as well.

U3L4W4 Secret

In cell block B, look in the cell at the human prisoner banging his fists against a portion of the wall. Shoot at it and crawl in to grab the Invulnerability power-up.

U3L4W5 Strategy

Kill humans crawling around to uncover ammo and other helpful items. To get out of this area, hop into any of the two grates at the bottom of the cell near the locked exit doors.

U3L4W6 Strategy

Activate the rebreather and swim in the underground pipes to the room with the security pass.

U3L4W9 Secret

Step on the plate to lower the human into the lava, when it rises back up, collect the hyper blaster in his place. Then, activate the Invulnerability you found and hop into the lava to find a bunch of goodies at the bottom.

U3L3W7 Strategy

After returning from the detention center, use the hyper blaster to annihilate all Strogg left on this level.  Magnifico!

U3L5W2 Secret

Look at the crack in the wall - shoot it to uncover a secret area.

U3L5W3 Secret

When you head outside, press the odd-looking brick in front of you (sticking out). This will open the small set of stairs to reveal an adrenaline power-up. Be quick though!

U3L5W4 Strategy

While outside, reach for the combat armor but beware of the Mutant hiding behind the wall. 

U3L5W4 Secret

Jump into the water outside and look for the mega-health pack at the bottom. Enter the small room to the right, killing all Strogg in your path, and crawl into the area at the back to find some secrets.

U3L5W4 Strategy #2

Now enter the second room just beside the water and be careful when you touch the hyper blaster. The ground will fall around you onto spikes so stay where you picked up the weapon and you’ll be ok. If you do fall in, and you don’t land on the spikes, look for a ladder to take you back up.

U3L5W5 Strategy

Kill the Tank as you did before - use the wall for cover and use something powerful to peg him off when you can. Just take turns firing at each other. When it’s dead, press the button behind its body to get inside.

U3L6W1 Strategy

Time it so you can squeeze by the blue lasers to collect the armor and grenade launcher. You will need to use the same technique in a moment.

U3L6W3 Strategy

While outside, kill all the Beserkers and the Super Tank is next. Use the pillars for cover and when you get a good angle while peeking behind the pillar, stay with it and he’ll be down in no time.

U3L6W4 Strategy

After you’ve killed the Super Tank, jump into the hole where he emerged from, press the button, and destroy the blue crystal laser to finish the unit.
