If you didn't already know it… you should. There's a ton of killing in Assassin's Creed. It doesn't matter if you're killing templars, civilians, stupid guards, or heavily armored mercenaries. You. Just. KILL.
So it's no surprise that the multiplayer modes in Assassin's Creed: Revelations will feature even more killing. It'd be such a let down if in multiplayer all you did was hug. The sneakier the hug the more points you get. You'd get the most points if the person you hugged didn't even know you were hugging them…
until it was too late.
Thank God Ubisoft is taking this opportunity to remind us that you actually do kill people in multiplayer. Lots and lots of people… killed… per second.
