New Halo 3 Map Unveiled
'Narrows': a massive bridge over the misty void. First screens inside.
by Patrick Kolan, IGN AU

Australia, August 15, 2007 - IGN AU just came out of interviews with Lars Bakken (Multiplayer Designer) and Frank O'Connor (Writing Lead) at Bungie. Straight from Lars, here's the description of the newest map, 'Narrows':

"It's a Forerunner structure. It's embedded in this cliff wall and it's a bridge. Imagine the - if you're familiar with Halo 1 - imagine the bridge from Assault on the Control Room, expanded, and made for multiplayer, so it's got multiple levels and each side has kind of a dug in section, and it's mirrored so on one side of each of the bases there's actually a Man Cannon, and if both sides take it at the same time they'll actually meet in mid-air, which is pretty cool.

"There are multiple areas that you fight over; there are some power weapons in the centre of the map. I'll give you guys a heads-up right now - there's actually a rocket launcher on top and a shotgun on the lowest level dead centre of the map, so when you guys play it tonight you'll have a little extra edge on the competition…"

We'll have full hands-on impressions of Narrows, as well as the two interviews and some hot event coverage coming tomorrow and into Monday. Stay tuned.

Narrows - a multi-level Forerunner structure with twin man-cannons that can cause players to collide in mid-air.

The bridge is set into two cliff walls over a cloudy void in the mountains.

This game just keeps looking better and better.
