Now that the Euros and Aussie are close to having or already have their hands on Assassin's Creed Brotherhood, Ubi has a new gameplay-ish trailer explaining a couple new features found in the sequel to a sequel -- full synchronizations and VR training.
The former adds extra objectives to memories (missions) that need to be fulfilled for 100 percent completion. Otherwise, you're stuck with only 50 percent, and that tends to annoy completionists. Going through the trouble of achieving full synch in every memory rewards the player with hidden memories, like stalking Ezio's first girlfriend.
The virtual reality training is pretty straightforward. Access it via Animus Desktop and go through a series of VR challenges, then see how you scored against other players online.
Now we know some of you still aren't sure about Brotherhood because it's still in Italy and keeps the hero from ACII. Rest assured, the game rocks pretty massively even without a Roman numeral in the title; just stop thinking of it as an expansion.
