Since Agent Ada Wong’s appearance as a playable character in Resident Evil 6 was revealed last month via mining files on the demo, there has not been very many official details regarding what exactly her involvement in the game is going to be.
Wong will have her own complete campaign which will be unlocked after the main game is completed. She will be acting all alone,unlike the Leon, Jake, and Chris campaigns. Rather than focus on one major theme, her campaign seems to use puzzle elements, combat, and huge set pieces in harmony. Her story will apparently help the player see the other three
characters from a different perspective.
Check out the Ada reveal trailer.
As for the new Agent Hunt mode, players get to see Resident Evil 6 from yet another perspective. Inspired by the ‘invasion’ mechanic from Demon’s/Dark Souls, this mode allows you to enter a random person’s game as a monster (type depends on where at in the campaign you jump in). Up to two playable monsters are possible, as teamwork is the key to killing an agent.
