"Cliffy B is promising lots and lots of blood. The example he gave was Marcus will leave trails of blood on the wall when he is in cover while injured."
^ This is what's wrong with Gears, too much attention to blood, gore and "badass-ness", and less on adding variety to the gameplay and multiplayer.
I hope I'm wrong, but they have a long way to go to improve Gear's 1's multiplayer, which was downright repetitive and lacked any variety.
