Just walk as nearer to the fence as possible (must be an electrified area of 2 meters around that pole) (Image 6). Crab & crates downstairs & upstairs. Damn, these crabs have super speed.

Break the window and jump to reach the wall on the right and hug it (Image 7). Enter the generator control room and turn off the electricity. Pick up a trip mine on the right. Go through the last door left. Map change.

Go through the storage and take Barney. Up the stairs. Map change.

Bombing Surface

Crates, listen to the scientist. Step into the hall and activate the turrets, then go back and wait for them to deactivate. Same in the next 2 hallways. Time to use your bow on the 2 grunts up there. 2 grunts dropped by a chopper. Run inside. 3rd grunt. 2 more down there, but hurry & get on the other side (Image 20) for 3 more will be dropped by another chopper.

Notice the kaki chopper (Image 21). Check the crates. Go inside. Grunt. 3 more upstairs. While you’re checking the crates, grunts keep being delivered, no need to waste more ammo. Go through the electrified fence (you could try bombing the blockage on the door from the broken window, but it didn’t unblock in my case).

Run towards the open door (Image 22). Go right, recharge and turn the valve to open the hatch. Use Barney to unlock the goodies. Take down the chopper with about 4 rockets, then the grunts and go down the hatch while the place is being bombed. Map change.

Pick up the snark and the ammo and run! Super crabs are after you. The zombie doesn’t matter. Let the 2 bullsquids as lunch and climb up the ladder. Run a bit, run some more. Zombie. Map change.

2 assassins & a grunt or 2. Check the crates & the big truck; go right. 2 turrets guarding the door. Before entering, take down 3 grunts & a turret. Machine gun on the far right. 4 more assassins and you’re done. Enjoy the crates & goodies, mind the snark. Take the small door (Image 25). Avoid the barnacles. And stand in the doorway to trigger a war between assassins & Xen creatures.

If a ninja comes in for you, lure him into a barnacle. You can take care of what’s left in the same sadistic way… (Image 26). Take the small door. 2 more assassins. Trip mine. Map change.

Trip lasers & houndeyes. No need to check the restroom (assassins & health). Through the Freight Records room, turret and get outside. Some sort of zombies with guns and some crabs await. At some point, use the bow on the zombie grunt high on some box before approaching that area. Check everything, every truck top, bottom, inside & out, that small door (if you want some slaves, alien grunts & zombie grunts to appear). And finally, the vent system (Image 27). Be my guest and try to get the goodies on top of it. Then enter it. Crabs.

Go until you reach the end of it (health & hev). Kill the grunts & slave from up here. Exit through the last grate and jump from box to box to get to the arrows. Careful, another zombie near them. Now go back on the red box and jump on the one next to it and enter it (Image 28). Release the scientists. You can check the crates and the boxes now. Take the scientists to the door. They will open it, but soon some grunts pop out, so take them inside and watch your back.

Now take a walk with the scientists and protect them at all costs. At the parking lot, another war breaks. Just leave the scientists behind and secure the area. In the tunnel, a ninja, a crab & a zombie grunt. Another portal opens up. Barney (if you left him there) will run to the scientists. You can clean that area for them from up here (Image 29). Take all 3 with you. Careful, you can use only 2 at a time. Take the elevator. Push a scientist out of it and take him to the CommLink panel, he’ll open the front door. Tunnel.

Take the turret on right before tripping the sensors. 4 hard to shoot assassins. Clear the area, then bring the scientist to the glass door with the turret. Shoot the trip mine on the right. Check the storage, after you break the lock. Kill the slaves when you come out. Check the booth with 2 crabs & a zombie. Watch Barney die (Image 30) and step on him to take 5 snarks. Turret. First floor again. Climb down, take out the first zombie and let the next one, or a crab, trip that mine. Crates & a baby crab in a storage.

Now go up. Turret, as you can hear. Same thing with a zombie & trip mine. Break the glass. You see the door is blocked heavily. A well-placed grenade will fix that (Image 31). Unblock the next one in the same way. Throw a grenade to trip a mine & kill a zombie & a crab. Throw a second grenade in the storage. Turret. Recharge. Now you can take the big door on the right or you can go back, which for me was a dead end. Now a big parenthesis with what happened there.

(Walk about. 2 zombies in the tunnel. Take healed Barney with you and take the elevator which takes you up or down, to random levels as it so fits. Gargantua round the corner. Use a variety of explosives but leave some for the next garg. 3 zombie grunts in the tunnel. Next, a Garg & several grunts. Just run to the left corner and take the grunts from a distance – easy targets as they walk slowly. Then, the garg. I even used my snarks on him, for their small explosion when they die out. Bring a scientist to try and open that door. Grunts pop out. Sounds of a variety of enemies and that’s it.)

Take that big door. Map change.

I took the first six ninjas with the crossbow, then the other 3 with the Colt. 4 more ahead. Throw a grenade at the turret and go in the control room. There’s a lever in the small room that brings down the turrets, a lever which I’m not sure you have to pull. Just break the glass on the panel (Image 32) and activate it. Recharge. The fence is sliding. Approach the elevator and throw a satchel at the grunts in it. Take the battery from the truck, recharge for health and take the elevator. Grunts. As you pass the truck, more grunts. At the end of the tunnel, several grunts & turrets. Go to the control room, push the button to close the gate (more grunts coming) and wait for the big door to open. Greet Barney. Move along. Crabs & crates. Pull the lever near the big 35 and wait for the turret to kill the slave. Watch out for the invisible crabs. Open the door & run backwards. As the slaves go through, shoot the cylinders on the left. This time you won’t need the turrets. Crates & crabs.

Shoot the cylinders in the far left and take the door on the right (Image 33). The next door is a killer to stand in. Just wait for 3 grunts to open the door, one after another… get out, lure 3 more. Get out, left, zombie, crab & slave. Don’t get out of your hiding place too much, there’s an unreachable machine gun. Aim (with the bow) the top of the grunt’s head. Slaves. 2 more crabs and the coast is clear for now. Go to the small door in the corner. Grunts pop out. Lots. After finishing them, recharge in that small room & take the elevator, 2 zombies. Listen to the scientists then kill the 2 grunts in the hallway. Third on right. Door in front. Zombie & crabs. Another crab & snarks. Oh, and another invisible crab (this is why I hate this mod; well, this and getting shot in the doorway). Zombie, then take the tram.

Distortion

Another really annoying thing, the tram ride as a sitting duck and the gay voice. Finally, a change of scenario. You wake up with no guns. Downstairs, a clip. Upstairs, a zombie. Just get pass him somehow (lure him downstairs to have more room) so you can reach the crowbar in that storage. Then hack the zombie, check the crates and the Out of Order sign and activate.. something in that room (Image 34). Now you can go outside. Crab comin’ for ya & no gun. Dodge it & go right, grab Barney’s gun and now we’re back in business. Run to the ladder on the left. Barney & a shotgun. Crabs & an elevator cliché, but harder because of its ledges. Just climb, enter the elevator and approach the door.

Upper Yard

Run behind the high voltage thing and approach the 2nd turret. 2 crabs & waste. Use the right table to pass. Grab the clip & hide, grab the clip under the window, then run (health, anyone?).

Activate the panel, wait for the door to open. Finish the aliens behind the door, check the crates & the truck, recharge & take a deep breath. The big door blows up in front of you but don’t go through. A tank shooting rockets, a turret, a machine gun & a bunch of assassins, all just for you. Plus, behind you, 3 assassins that caught up with you. Make use of your crossbow & Magnum. After you take down everything in sight (except the tank), approach the tank and shoot the assassin behind it (Image 38), then go back. Now jump into the trenches (rarely used, but cool idea) on the left. RPG. Throw grenades at the tank (about 7 on medium skill).
