Currently the ABT page and Light Field and Sean's pages all highly imply they use ABT. Upon playing the Virtue's Last Reward (where ABT was introduced to the franchise) again, it turns out there is further information in the game which contradicts or at least debunks what is written on the wiki pages.
In a secret gold file titled "GAULEM", it's stated that ABT was created by Sigma Klim as Zero Sr. While it's true that for a time, Dr. Klim's consciousness jumps back to 2028 near Sean's appearance in the timeline, it's only a matter of a few days that he's present before ZTD takes place and it's unlikely he could just make it for no reason.
As for Snake or Light Field, his appearance in 999 takes place before both games so it goes without saying that there's no way he could have ABT. I can only assume that before ABT there was some other, more crude version of it made which both Sean and Light Field have.
Anyway, do you believe the pages mentioned should be edited to add Zero Sr.'s involvement in creating ABT, and removing instances of ABT from Snake/Sean's pages?

The GAULEMs have nothing to do with the topic besides the fact that they use ABT and that the information stated here was taken from a VLR gold file titled "GAULEM".
The main point of this topic is that the gold file states that Sigma Klim/Zero Sr. created Artifical Biological Tissue, which would have been made well after ZTD and 999's events and subsequently the characters implied to be using the yet-invented ABT. Since this wiki strives to use accurate/confirmed information these edits should be made to the pages.
