Role
A hacktivist hailing from Sierra Leone, Hall met a mysterious man named Lucas Grey and became partners-in-crime with him, later becoming the right-hand woman in his Private Militia. Together, they assassinated members of Providence, a shadowy organisation that secretly controls the world.
Hall was tracked down by the International Contract Agency, who sought revenge after realising that they have been tricked by Grey into killing his specified targets. Hall fled just in time and four of her colleagues were killed instead, leaving her wrecked with survivor's guilt.
A year later, the ICA, acting on Providence's behalf, killed several more militia associates, to Hall's increasing panic and frustration with her boss. Grey eventually led the assassin behind all the hits, Agent 47, to the asylum and revealed that they were both clones created by Otto Wolfgang Ort-Meyer. 47 and his handler, the inscrutable Diana Burnwood, join forces with Grey and manipulate the ICA into killing Providence's former Constant, Janus, and his head of security Nolan Cassidy.
Gathering intel, the four are able to kidnap the current Constant and interrogate him into revealing the names of the Partners. Hall hacks into the Milton-Fitzpatrick Bank and the Haven Island servers to discover the names of the Partners, but then discovers that one "Arthur Edwards" had stolen all of the money from the Partners. Diana deduces that it's the Constant's name and rushes to his cell to find it empty. The women alert the men, who ignore them.
After 47 and Grey kill the Partners, Grey is cornered by CICADA mercenaries and commits suicide, while Diana switches sides and joins the Constant. Hall flees to Berlin and is ambushed by the ICA, who discovered 47's treachery and plan to kill him, Diana and Hall. Hall kills one of the agents while 47 handles the rest. Reuniting with Hall in a diner, Hall reflects on her first murder and mourns Grey before helping 47 track down ICA HQ in Chongqing and killing ICA officials Hush and Imogen Royce.
Hall makes her last appearance doing one more favour for 47, tracking down Diana to a vineyard in Mendoza. After expressing her doubts over Diana's loyalty, the hacker bids 47 farewell and hangs up.
