The mission requires secrecy. Failure is not an option. Play as Ada Wong in this additional scenario and experience the events of Resident Evil 4 from her perspective, filling in unanswered questions posed in the main story. In addition to the action available in the base game with Leon, a grappling gun can be used to get to various locations, as well as take down enemies from a distance and launch a ranged melee attack. This allows for a more exciting and fast-paced gameplay experience.
