im looking in the timeline on the wikia..
the name FEV was coined in 2075, while at west tek..
February 2077: FEV Research is leaked to the world through an unknown source
vault 87 didnt close until 2078
how hard would it be if that research was leaked, for the actual data to be known by other scientists? the computer in 87 saiys "this strain" meaning its clearly not the acutal FEV from mariposa. but an unkown source leaking the FEV research also means jhat the amount of info on FEV is unknown..
October 23 2077: The Mariposa Military Base survives, the soldiers and scientists within protected from the radiation and
FEV flooding the wastelandhmmmmmmmmmmmmmmmmm, but its tightly under wraps?
also, if thats not enough for you..
once a term is coiined most things that are "like it" use that name.
people say "i want a coke" when they may not mean the namebrand, but just a soda, or pop...
If the term FEV was coined that early and the whole world knew the name "FEV" it could stand to reason that even if it isnt the same FEV, thats what they are calling it because it does force evolution-why come up with a new name.
surely these three scenarios can cast a shadow of doubt that FEV could only be exclusive to previous games..
