The recently released Resident Evil 6 demo may have inadvertently revealed a currently unannounced campaign starring Ada Wong.
The game already features three campaigns with different gameplay styles for Leon Kennedy, Jake Muller and Chris Redfield, but data files hidden within the demo's code and unearthed by NeoGAF and GameFAQs members suggest a fourth story section could also be included (or maybe released as DLC).
Rumours of an Ada campaign did the rounds back in January, while Eurogamer reports that a fourth main character was hinted at by a "secret" face on the packaging of the very pricey Resident Evil 6 Premium Edition.
Asked for comment on the data uncovered in the demo, Capcom told the site: "While it is correct that at E3 we confirmed that Ada Wong would feature in Resident Evil 6, we have no comment on the reports that are currently circulating."
A Resident Evil 6 demo hit Xbox Live earlier this week, although it's currently only available to download if you own an Xbox 360 copy of Dragon's Dogma. The Resi 6 taster will be exclusive to Microsoft's console for two months - those with the PS3 version of Dragon's Dogma will be able to play it from September 4 in the US and Japan, and September 5 in Europe.
The demo offers Leon, Chris and Jake sections - check out one in the video below, and view the other playthroughs here.
