Secret Intelligence Service

Secret Intelligence Service, commonly known as MI6, is the foreign intelligence service of the government of the United Kingdom.

History
MI6 came to Lara Croft in her manor to ask for her assistance with Jonathan Reiss, because they know he plans something but not what. Lara had a run in with one of Reiss' associates from Shay Ling earlier, and took it quite personally. Lara managed to convince the MI6 that she needs the help of Terry Sheridan, and have him released from Barla Kala Prison in Kazakhstan.
