One of your modules doesn't work, as I'm sure you're aware.
The opening RAISA warning is too casual, make it sound formal.
Don't include a smiley face in the message, add after that there was a crude 'happy face' carved after the message.
Add more than "this is theorized to connect to SCP-6000"
There wouldn't be a dash between 0.5 and meter
You didn't replace SCP-XXXX-A with SCP-6000-A
I feel you mislabeled these different components. When you classify something as SCP-XXXX-A, -B, or -C for example. In my experience those are reserved for specific components of a whole, such as a single individual. I'll give an example below.
SCP-XXXX-A is a man who can open portals into other dimensions. SCP-XXXX-B would be his cane, which he uses to create the portals.
Also in my expeirence, classifying somehting as SCP-XXXX-2, or -3, is to group a larger collection of individuals. I'll also give an example below.
SCP-XXXX is a woman who can create bunnies when she pulls them out of her hat. Those bunnies would be classified as SCP-XXXX-2.
Also if I misunderstand this system, please feel free to tell me.
You say the SCP-6000-C can stop the SCP-6000-B from dying, but you should go into more detail on this.
Wait wait wait. So this tree sprouted from the ground, and these people were trapped inside. So the MTF just said "Yeah whatever" and left them in there?? Yeah it caused heavy damage to the roof, but that's not even close to dangerous for the MTF.
You introduce this new MTF, MTF Lambda-1, but you don't actually describe what they do. You should add a footnote briefly detailing what they do.
I feel like the interview is kinda crlunky. Either re-write bits of the SCP-6000-C's dialogue or extend the interview to have SCP-6000-C leaving the interview or something like that.
Addendum 2 is a bit off, all the text just kinda clumped together. Either add dividers or add larger gaps in between the text.
Wait you're introducing another Lambda-1? Why?
The nickname would have parentheses around it: Armed Command Battalion Lambda-1 ("God's Children")
Dr. Thervene wouldn't be referred to as Dr. Cole in the interview log transcript. SCP-6000 could mention his name, but his title in the transcript should be Thervene.
(Also a side note, Thervene is a cool name)
Small detail, but when you get Thervene to say "Get the paramedics, check on them." you should say instead:
Dr. Thervene: [Talking to Project Head Insert Name) Get the paramedics, check on them.
I like how you end that transcript as well, very good stuff.
I also just noticed this. In the pre-interview description, you don't add the period to Dr.
Your link to SCP-990 is messed up and doesn't work.
Utilizes is spelled incorrectly in Addendum.6000.3
I feel like Dr. Dre is on the cusp of me not liking his writing. He swears a lot and while I get his frustrations I don't think he should swear that much.
You call Dr. Dre both Dr. Dre and Dr. Smith. I thought Dre was his last name, you should make that more apparent.
You say "This bitch almost took killed everyone there" in the interview, make sure to delete either killed or took.
In the final revision the ACS is a bit off, either change it slightly or keep it there as it is.
The ending is a bit meh, it's alright. It doesn't strike me with any emotion.
