Note: The Mark II can also be pulled from the box. Use the Gum “WONDERBAR” in combination with the Gum “CRATE POWER” to get the weapon directly at Punch Level I.
If you want to get the Ray Gun the “regular” way, stay in the main mainframe chamber. A lab technician will appear starting at round 10 or later.
Kill the lab technician, and he will drop a floppy disk that you must pick up.
Now, head to the East Foyer and look for the computer. Interact with it to insert the floppy disk.
Right next to it, a fax machine will start working and transmit a message to you. Warning: During this time, a lockdown will be triggered, and some creatures will spawn. Once the fax is finished, you can interact with it and read the message.
In the message, there will be a keyword that you need to remember or write down:
- Moth
- Yeti
- Crab
- Worm
This word must be converted into a four-digit code. To do this, you need to consult the following chalkboard in the nursery:
To convert the letters into a code, examine each letter individually. In our example, the word is YETI. Now, take the letter Y and look for its position on the table. We see that the letter is located at the far right of the top row. Now count the number of letters in this group. In this case, there are 5 letters. So, the first digit of the code is 5.
We repeat this process with the remaining 3 letters, and we get the following code: 5482.
Now, head back underground to the service tunnel. There, you will find a Doppelghast trapped behind a glass gate.
Next to the gate, you will see a keypad. Head over to it and interact with it. Now, you can enter the code from the letters.
After entering the code, the gate will open, and the Doppelghast will be released. Kill it, and it will drop a severed arm that you can pick up.
With the severed arm you just picked up, head to the armory. It’s located in the room with the teleporter. At the end of the room, you’ll find a display case containing the Ray Gun Mark II. On the right edge of the display case, you’ll see a lever. Interact with it to attach the severed arm to it. Now, you can pick up the Ray Gun Mark II.
First, we need a canister, which can be found at three different locations. To simplify, we will mention just one of the three possible locations.
On the map, there are four places where a type of crystal can be found. These look as follows:
These crystals can only be destroyed with the Ray Gun Mark II. If you hit the correct crystal, a canister will fall down, which you must pick up.
Now, go to Shem’s Henge and insert the canister into the following apparatus:
Next, two abominations will appear at the stone circle. You must not kill them, as they are necessary to charge the canister.
The abominations must now shoot their beams at the three small stones. You will know it worked when the stones begin to glow blue.
Now, one of the creatures must run into the glowing stone, and it will start to levitate. Once all three stones are floating, the abominations will disappear.
Now, you must protect the apparatus in the center of the area. Once you’ve done that, you can pick up the charged canister again.
Now, take the canister to the supply depot and insert the canister into the following machine:
Press and hold the interaction button to upgrade the Ray Gun.
Equip yourself with Tomahawks. Tip: Tomahawks are scattered around the map, and you can pick them up.
Now, head back to the mainframe chamber and locate the following tank. To the left of it, there will be a letter on the wall. Remember this letter.
It will either be the letter A or the letter B, so you don’t have much of a choice. Remember the letter you found.
Now, head back to the service tunnel and look at the following wall. This is located directly to the left of the gate where we freed the Doppelghast for the Ray Gun.
You will clearly see either the letter A or B. So, if the letter next to the container is A, you need to hit the top red valve with the Tomahawk, then hit the second one further left. If you have the letter B, you’ll hit the bottom red valve and then the second one on the left.
Once you’ve hit both valves, a voice line will play. Now, head back to the container where you noted the letter earlier.
Equip a Semtex and throw it at the shattered glass. It will break, releasing the next canister.
Pick up the canister and begin searching for the next part. It’s a bomb, which can be found in one of the following boxes:
The boxes are scattered all over the map. Shoot at the boxes, and they will break open. Pick up the bomb.
Now, it’s time to search for two reflactors. The first one can be found in a fountain near the southwest balcony and the conservatory. Simply interact with the fountain, and you’ll get the corresponding part.
Once you have the reflectors, head to the service tunnel and interact with the following wall:
Once the bomb has exploded, a hidden room will become visible. Place the canister back into the machine in this room to fill it.
You will now notice a blue beam. Follow the beam to its end and interact with the post to place the first reflector.
In the room, you’ll also find a second post where you can place the second reflector.
Now, you need to adjust the reflectors so that the beam is directed at one of the three Doppelghast statues.
You can adjust the reflectors by hitting them.
Once the beam is directed at one of the statues, hit the blue crystal from which the blue beam originates.
After a short time, the statue will transform into a real Doppelghast that you must defeat.
For the third statue, you need to pick up the mirror you placed second by interacting with it and place it on the third post.
Once you’ve defeated all three Doppelghast, you can pick up the canister again and craft the new version of the Ray Gun. Head to the Director’s Quarters, insert the canister as usual, and craft the Ray Gun Mark II-P.
For the third and final Mark II variant, you need to search for parts again. The first part is the third canister, which is located right behind Double Tap at the following location:
To get the canister, you need a casemir. This can be crafted at the workbench. Throw the casemir directly in front of the opening and wait until it’s finished.
Once it’s done, you can pick up the canister from the floor.
Now you need to collect four plant seeds. For this, you need either Semtex grenades or napalm burst on your weapon. Search the map for the following plants:
Throw the Semtex at the plant, or shoot it with the weapon that is equipped with napalm salve. Afterwards, the seed will be released, which you can then pick up.
Once you’ve collected all four seeds, head to the conservatory and insert the canister into the following machine:
Now, you need to grow the plant seeds. To do this, interact with the following machine:
Now, you need to protect the seed. Defend the seed until it is fully grown.
Repeat this step with all four incubators until all four seeds are fully grown. After that, grab the filled canister and head to the spawn area to obtain the next Ray Gun variant.
