The myriad firing positions both below and on the catwalks above make for interesting options. A good example was a capture point on the north western corner of the map, huddled in an alcove with more than four direct lines of sight, which became the last stronghold for the opposing team in a round of the Territories mode. With proper coordination, Ghost Town allows for pretty spectacular firefights--and unlike other scenarios, it's actually possible to hold out.

Meanwhile, the map's jungle fauna, rocky terrain and crumbling surroundings keep repeat play fresh—checking your corners isn't as simple as it is in, say, Epitaph, and a good team will always find new and interesting ways to kill you. The map is large enough to maintain tension, but not so large that you can't make the distance in time. Great for One Bomb, One Flag and Territories.

Having whipped the attending journalists into a bloodlust, Bungie moved us onto the third and final map demonstrated that day, a throwback to the days of Halo yore.

Avalanche
Once again, it's important to note that I wasn't really part of the living room revolution of the original Halo's heyday, and as such have little experience with Sidewinder. But from what I've seen on Google image search, it's gone through a huge visual makeover, appearing now with a much grander skybox and more detailed terrain features than was seen in its predecessor.

For those similarly uninitiated players, Avalanche is a horseshoe-shaped snowy valley with two bases situated on either end, separated from one another by high cliffs. Two access points connect the bases, one on the far south end accessible to the larger vehicles, and an infantry passage for quick trips. Those access points are themselves connected by a cavern, making swift defensive runs a breeze.

Being a sucker for large-scale battles--something Avalanche does particularly well--this was my favorite map of the day.

Though the map works okay in straight deathmatch modes, Avalanche's size simply screams objective gametypes, and includes some tweaks to make things interesting. One-sided objective games are outfitted with asymmetrical vehicle setups, UNSC on offense and Covenant on defense. The vehicles respawn fairly quickly after being destroyed, and the persistent presence of armored transport and assault vehicles keep the fights brisk.

Going in I was a smidge concerned that I'd spend a lot of time running from A to B, but the battles graciously played out much quicker than I had expected. Unlike similarly huge maps, Avalanche plays lightning quick.

Players familiar with Sidewinder will notice the addition of new mancannon placements at key points in the map. Of particular note are those structures placed just in front of and just inside the two bases, making fast entries and exits critical to success.

The developers made sure to point out that not only could infantry launch themselves into the gaping maw of the enemy base, but infantry loaded onto a Mongoose or Warthog as well. This tidbit of information gave rise to some of the most comical—and effective—tactics in the following matches.

The order of the day in Avalanche is battlefield management—knowing where your enemies are and making good use of your available arsenal. While the level is indeed massive, skirmishes tend to localize in and around choke points, such as the quick cavern route and base entrances. The inclusion of the Hornet and Banshee tends to discourage stragglers on the level's outlying areas, promoting more direct routes and swift transport as better means of keeping yourself alive.

Fans of Sidewinder will undoubtedly welcome the return of the map in Avalanche, and new players will also appreciate an alternative to Valhalla for large-scale warfare. Featuring a not-quite-linear layout, Avalanche supports an array of different play styles, ensuring a lengthy shelf-life—definitely my favorite pick among the three.

Bang For Your Buck
Recommending a map pack, like any other expansion, more or less depends on how much you play the original game. If you were never enraptured by Halo 3's multiplayer, it's doubtful that these maps are going to change your mind.

But those fans who live and die by their rankings, who still play on a nightly basis, will definitely appreciate the mileage. The experiences available in the three maps are very distinct from one another, and should make for some compelling battles as players discover their quirks and nuances. More maps mean more variety, and that's something the Legendary pack definitely offers.

The Halo 3 Legendary Map Pack will be released as an Xbox Live Marketplace download on April 15, selling at the price of 800 Microsoft Points ($10).
