to put some hope in your heads which are busy shedding tears at the moment, there is still the possibility of Bungie releasing a blood gulch remake. first off, i think that Valhalla is a great map, and is on of the few maps I NEVER veto, but it just doesnt offer the experience of blood gulch or coagulation. back to the point, note that Bungie has only announced one map so far, so whos to say that say, longshore, isnt Blood Gulch? also remember that Bungie has a very proactive fan base, who makes sure that Bungie knows what the fans want, and Bungie has done an equally good job fulfilling those requests, case and point Blackout/Lockout. so I dont understand why everyone is whining about Heretic being Midship, it seemed that everyone loved midship back in Halo 2, and due to the Halo 3 experience i imagine that it will be just as fun and, very, very, shiny. What im getting at is that there still might be a Halo 3 Blood Gulch.
Sidenote: if they were to re-make Blood Gulch, what would they name it?
