No, they do not need to be alive (War fell of a bridge, R.I.P) , just make sure you find them all. Find famine, then get Death by either finding him yourself, or by beating the Undead Nightmare campaign. Once you have Death, you complete a challenge in which you must kill each kind of Zombie with Death (pretty easy considering, much like war sets zombies on fire, Death makes their heads explode), once you do this challenge you'll get the blood pacts to the horses.
Trying to complete the Uncharted 2 campaing for the second time. One of the best games I've played.
hi
Paper Mario. Playing it all the way through for the first time. (The first time I actually pplayed this game was ten years ago, and I only made it to Forever Forest...)
But now I'm at Flower Fields and ready to kick ass

Just did all of the side missions in Sonic Generations. Now it's time to find the red rings. I also went on a mass killing spree in Skyrim. God I love mods.
