Office Complex

  1. To your left there will be electrified water. Head right and watch the scientists get attacked.
  2. Head back and go through the broken wall. Take the vent to the room where the scientist was killed.
  3. Find the scientist cowering behind the chairs. Move into the room in front of him and hit the power. Go through the doors and cross the previously electrified water.
  4. Break the window and jump through to the next area. Follow the red lights and kill the zombies that will attack you. Go through the red doors and find the security guards.
  5. Pick up health at the bottom of the room, and head back the way you came in. Near the window you entered the area through will be yet another breakable window.
  6. Jump through the window and use the furniture to move across the room. Hopefully you’ve played enough ‘the-floor-is-lava’ to know how to safely cross to the vent without being electrocuted.
  7. Kill the headcrabs and crawl through the ventilation until you fall. Climb up the nearest ladder into the vents again. Break through into the next area and avoid the turret.
  8. Hide behind the first crate to avoid getting shot. Use the crates as cover and move towards the lift. Destroy the turret and raise the lift. There will be a small passageway containing a power switch. Throw the switch.
  9. Head up the stairs until you reach another security guard. Open the red doors and kill the enemies inside.
  10. Find the barricaded office and push your way in. Find the scientists and lead them out of the room towards another set of red doors.
  11. Near the stairs, you will find another scientist who will inform you soldiers are coming. Continue up the stairs.
  12. Destroy the turret guarding the stairs and open the next set of doors. Move right into the hallway and kill the enemies. Break the entrance to the vent and follow it to the fan.
  13. Use the ladder to reach the power switch and power down the fan. Clear the gap to the fan and climb into the next vent. Follow it until you fall through the floor.
  14. Head out of that room and reach the cafeteria. Jump over the debris and go right down the hall.
  15. Kill the enemies and throw the switch to open the freezer door. Save the scientist from the attacking zombies.
  16. Find the valve on the floor and move it into place on the wall near the hanging meat. Move the meat directly across from the vent.
  17. Use the shelves to reach the high-up vents. Break the vent doors and continue through until you reach the bridge you made using the meat. Keep crouching through the vent until you reach the next room.
  18. Climb up the ladder onto the catwalk. Avoid the explosion, and go back down the ladder. Turn the valve, and move back up to the vents.
  19. Drop down to the security guards and the scientist. Walk up the stairs and kill the attacking enemies. Go through the exit door.
  20. Jump across the elevator shaft to the ladder. Keep climbing until you see a scientist barely holding on to the ledge.
  21. Walk across the wooden plank to the platform adjacent to the hanging scientist. Keep going up until the elevator falls.
  22. Jump on top of the elevator and break through into it. Take the elevator to the next area.

This “walkthrough” sucks. The character cannot even jump at all and many of the puzzles cannot be solved according to what this says. I have had to complete them using other means, such as stacking boxes up to get out of an area because the SOB can’t jump!

Now I am stuck in the sewage area at #15! BS!!! You can;’t avoid them and you can’t slow down! F this “game”

You can jump ( space then ctrl )

Missing out KNERD, just beat the game and had a lot of fun. the puzzles are headache level hard, but you’ve got to master the ctrl-space jump and shift-jump to solve the puzzles.

i found this walkthrough pretty strange , it seems to be mixed up with the original halfelife , i have got to lambada core and i am going around the cliff, up i go but cant jump any further , this part is not even in the walkthrough , and also agree it is not possible to jump some of the distances (and yes i do know about using the ctrl key) so you have to build a platform with drums and pallets , score out of 100 would be 30 , i wonder if this person has ever played the game ,

@Crusty,

Hey crusty! We’re here to help, but we’re going to need a little more information to solve this problem. Can you list which part of the Lambda Core guide is giving you trouble? Just a number of the entry is fine.

Sorry for the inconvenience! Also, make sure you’re using the Long-Jump Module when that becomes available in the Lambda Core, or Shift+Jump to make longer jumps when necessary. Many of the jumps can be tricky, but if you’ve still got problems, we want to help address them.

ok Kevin Thienhaus ,, fairs fair , first off i’m disapointed because Black Mesa is great in some ways better than original ,. OK where i am at present is “bm_c2a5c” up the cliff where i have to do a massive jump it looks like to get up the top , i will go back in my saved, to start of lamda core and find the long jump module , but from memory when you have passed that , you cant go back , if that is so then you should not be able to bypass it , i’m a bit confused on where the walkthrough is upto (as for me i’m always confused ) but it would be 13 onwards, and where is the part about going around the side of the cliffs ,, A bit of a ramble but i hope you get it

cheers crusty

#29-After activating the override, the water level will quickly rise. Swim towards the entrance and swim up to the ladder.

There is no ladder in the exit hole.

There is no ladder in the entrance/exit hole,so i can’t climb out!

@Jappy,

There is indeed a ladder — the first emergency exit from the sewers will have a broken ladder. Don’t fret, because if you’re going the right direction, toward the opposite side of the door you first dropping into the sewer from, you will find an exit with an intact ladder.

I love the game, but like the others, the character can not jump near high enough. If you could make him jump twice as high—-gosh what an improvement.

Try using your brain KNERD. You might find you actually enjoy gaming that way. Or you may just be better off just watching movies and fantasising you are the main character. This walkthrough is good to get a kick start on areas you get stuck on and Ive found it good. Gives you enough to keep moving but still lets you work stuff out for yourself. Good work guys.

I start generator, talk to the scientist, but after I reach that red button and press ‘E’ to start rocket, nothing happens.!!!
Please help me

@Faisal Aslam,

Can you pinpoint exactly in the walkthrough where you are having trouble?

If it is “Blast Pit” make sure to hit both red buttons. There are two, each in separate rooms.

This walkthrough is wrong, you don’t fight soldiers in this chapter

Kevin Thielenhaus

On July 1, 2013 at 2:37 pm

@Axale,

Can you tell me which chapter you’re looking at? I take pride in the accuracy of our walkthroughs, so if the information isn’t correct, it should be fixed.

In the original game, I thought I’d NEVER get the ‘Duck-Jump’
This one’s tougher but funses!
C’mon, KNERD

F’n EPIC!

Where the heck have I been?! Just started playing this and its 2013??? I never got to play half life 1 but I loved 2 n da episodes 1n2. But yea. This blows the orange box copy away. Though the crouch, jump, sprint is taking some doin…lol.

Great walkthrough. up until the blast pit part. I restarted the generator successfully, and the scientist told me power was restored, so i went back to the control room to hit the “fire” button, but the button won’t work. any other switches i have to throw first? its gonna suck to have to go back through all that.

@levi,

Hmm! I believe you need to return to the missile silo with the tentacle monster. There should be another path to go down that leads to the gas pumps. Get those working, and I think you should be good to go.
