The 'VAULT'

The 'VAULT' was originally a fallout shelter for the war in 2022. It was preventative messure in-case of nuclear exchange.
It was never used due to the fact they wanted to keep it a secret after the war.

Once GMG raided the UK, it is believed that the code was with a trusted and skilled soldier who was discharged from the armed forces by military leadership. Lawless are believed to now have this code.

The finding of the 'VAULT' will result in major loss to the BMF and will force a surrender.
