Rumour - Nathan Drake, Big Daddy to appear in PlayStation All-Stars

The PlayStation Facebook page may have accidentally outed two new contenders for PlayStation All-Stars Battle Royale.

Reports suggest a pair of polls on the official PlayStation Facebook page asked users who would win certain match ups.

Uncharted's Nathan Drake and BioShock's Big Daddy were listed - and pictured - alongside already-confirmed characters Kratos, Parappa, Fat Princess, Sly Cooper, Sweet Tooth and Colonel Radec.

The alleged polls were screengrabbed and posted to NeoGaf, but Shoryuken also claims to have seen them.

The two new roster additions join InFamous's Cole and Metal Gear Solid's Snake as officially unconfirmed but pretty certainly true inclusions.

PlayStation All-Stars Battle Royale is expected on PlayStation 3 during the holidays, with a Vita version unconfirmed but also leaking like a stuffed nose at a perfume convention.
