Ada Wong is a playable character in the upcoming Resident Evil 6. Players will have to complete Chris, Jake and Leon's campaigns in order to unlock Ada's story arc.
Famitsu reports (via Siliconera) that Ada Wong will be armed with a crossbow and timebombs. Unlike the other characters, Ada will not have an accompanying sidekick for her campaign.
It has also been revealed that Resi 6 will feature a new multiplayer mode called Agent Hunt.
Resident Evil 6 arrives on PS3 and Xbox 360 on October 2, with a PC version expected to release at a later date.
