Residue Processing

  1. You will awake with the soldiers, and your weapons, completely gone. Don’t take too much time to look around, because you are in a trash compactor. Use the boxes to escape before you are crushed.
  2. Enter the office on the other side of the compactor and grab your crowbar. Throw the switch to drop the boxes through the floor. Drop down to the floor and fall through the tunnel.
  3. Travel across the canyon until you reach a building. Climb the yellow tower and jump into the water. Use the valves to drain the water and open a tunnel.
  4. Travel through the empty tunnel until you reach a radiated room. Follow the security guard until he is killed by a barnacle. Head into the maintenance room and turn the valve.
  5. Move into waste treatment to where the radiation is. Move up the ladder and use the catwalk. Use the pipes to access a broken vent.
  6. Break the door to the vent and drop down to the ladder marked with a confined space sign. Walk down the hallway until you reach the room with pistons. The catwalk will be broken.
  7. Climb onto a piston and use it to jump to the next one. Avoid the radiation by using the catwalks, pistons, and pipes. Continue until a pipe bursts and the catwalk breaks.
  8. Walk until you reach the next waste treatment room. Walk across the pipes and platforms and jump onto the spinning device. Use it to jump to the door marked with a 3.
  9. Find the room with conveyer belts and drop down. Take one of the belts and drop down to the catwalk below. Jump into the dirty water and follow the current.
  10. Avoid being killed by the water treatment, and climb up the ladder to the walkway. Jump in the water again on the other side and swim down. Swim to the next room.
  11. Keep following the current while avoiding dangerous water treatment devices. There will be many rooms with health and ammo along the way, so feel free to explore. Exit the water in the room with a control room and stopped conveyer belts
  12. Throw the power switch in the control room and start the conveyer belts. Take the stairs to the right of the belts and throw the second power switch in the other office. Turn it off.
  13. The grinder will now be disabled. Follow the conveyer belt.
  14. Use the switch to open the door on the conveyer belt. Please disregard any signs telling you to stay off of the belt. It should be perfectly safe.
  15. Adjust your speed on the belt to avoid the many dangerous traps and pistons. You should reach a big room. Drop down to the next belt and continue forward. Follow the third conveyer belt down to a red door.
  16. Go through the door into a room with a control panel. Use the lever to move a hanging piece of belt to the middle of the room. Use it as a bridge and clear the gap. Follow the next belt towards hazardous fire.
  17. Time your movements and escape the fire. In the next room full of belts, drop down and ride the conveyer belts once more. Avoid any hazards such as mines and grinders.
  18. Once you pass final set of grinders and belts, drop down. Be careful not to fall into the grinder on the floor.
  19. Walk into the high-radiation room and climb up the ladder. Continue into a room with an electric fence. Instead of trying to find a way to the switch, just shoot the power switch through the fence. It will turn off.
  20. Open the door to the electric fence and follow the hallway. Turn left before the lab sign and enter 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

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.

Kevin Thielenhaus

@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.
