Assassin's Creed: Revelations (360) vs Dark Void (360)

When a man’s battles have been won and his enemies destroyed, what then? Where does he find purpose and meaning? To find answers to these questions, Ezio Auditore will travel east in search of the lost library of the Assassins. In Assassin’s Creed® Revelations, master assassin Ezio Auditore walks in the footsteps of the legendary mentor Altair, 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. In addition to Ezio’s award-winning story, a refined and expanded online multiplayer experience returns with more modes, more maps and more characters, allowing you to test your assassin skills against others from around the world.

Dark Void is a video game developed by Airtight Games and published by Capcom on the Unreal Engine 3 for the Xbox 360, PlayStation 3 and Microsoft Windows. In the game players must face an alien threat that humanity had previously banished. The game mixes on-foot and mid-air combat. The games make use of a new "vertical cover system", as well as a standard cover system.
The game will include a hover pack, and later, a jetpack, allowing for a quick transition between traditional shooter gameplay and flight. The game also features "tactical freedom", which is different ways of achieving the same goal.
