Two new trailers have come online for Ubisoft's Assassin's Creed Revelations and Bethesda's The Elder Scrolls V: Skyrim.

The first is the launch trailer for Assassin's Creed Revelations, which hits Xbox 360 and PlayStation 3 on November 15th, followed by the PC version on November 29th. In Assassin's Creed Revelations, master assassin Ezio Auditore walks in the footsteps of his legendary mentor, Altaïr, on a journey of discovery and revelation. It is a perilous path – one that will take Ezio to Constantinople, the heart of the Ottoman Empire, where a growing army of Templars threatens to destabilize the region.

The second is a "The World of Skyrim" trailer for The Elder Scrolls V: Skyrim, to be available on November 11 for the Xbox 360, PlayStation 3 and PC. The game reimagines and revolutionizes the open-world fantasy epic, bringing to life a complete virtual world open for you to explore any way you choose.
