Snowbound

Snowbound is a medium sized multiplayer map in Halo 3. From Bungie Q&A on a weekly update, they hinted that it may take place on a former Forerunner planet near Earth space, though it is currently occupied and being excavated by the Covenant.

Note about cardinal directions
Cardinal directions in this article are based upon Bungie's heatmaps. North is "up". In this article, the secondary map (with the numbered locations) is inverted, so north is "down" and south is "up".

Layout


Snowbound is a medium-sized, semi-symmetrical map set in a snowy Forerunner construct with two large Covenant bases at either end. The bases, known as high base and low base, are connected by an underground tunnel network. Several rock outcroppings are found around the perimeter of the map, as well as other Covenant and Forerunner constructions. A unique feature of this map is the infamous shield doors. Similar to those found on Epitaph, these doors stop all weapons and explosions, but let players pass through. Although Spike Grenades can stick to the shield itself, vehicles cannot pass through them. Due to map's structure, fighting often takes place in or around these shield doors. The most unique part of this level, however, is its boundaries. Here, automatic turret sentries will shoot any player who ventures out of bounds.

Low Base


Low Base is often referred to by players as "BR Spawn" due to the two Battle Rifles which spawn on the outer rear walls. Inside, you will find a Spartan Laser, two Brute Spikers, and a Bubble Shield. Outside the base spawns a Carbine, Spiker, Mauler (left side), and Active Camouflage (right side). On top of the base are a Needler, Plasma Rifle, and a pair of Plasma Grenades. This base's lights do not flicker.

High Base
Directly adjacent to Low Base, High Base offers a different set of weapons. High Base is commonly referred to as "Sniper Spawn" or "Carbine Base" due to the Carbine and Beam Rifle which spawn in this location. Behind the base, players can find a Battle Rifle or a Plasma Rifle around the rock terrain. Outside, players can find a Mauler to the left of the base, and an Overshield to the right. Inside, you will find two Plasma Rifles, a Beam Rifle, and a Power Drainer. On top of the base are a Needler, Plasma Rifle, and a pair of Plasma Grenades. The lights of this base flicker and buzz.

Upper Map


The upper portion of the map is home to many predominant features and access ways, and is also a Sniper's paradise. Located between both bases, to the south, is the Underpass (or "Ghost Spawn"), where a single Ghost (or Warthog) spawns. In the center of the map, you have access to the lower levels by way of the Ice Cave Tunnel. A common tactic for players is to blindly toss grenades into the map's lower levels from this area, utilizing the underground corridors and tight spaces to trap players in the explosions. Further to the north, on the opposite side end the Underpass, lies the Ice Cave's main entrance with its distinctive overhang and large shield door.

Ice Cave


Predominantly known as the "Shotgun Spawn", heavy fighting occurs in this cold and icy cave. This area sees frequent carnage, due to its high traffic, tight quarters, and position between the High and Low bases. To the immediate south is an elevated opening with no shield. West of this is the tunnel to Low Base. East of this is the tunnel to High Base. Directly south is the Main Entrance, which is protected by a larger shield door. Entering the Ice Cave from any of these 3 methods is usually extremely risky. This main entrance is very defensible, as it affords the player with a full view of the cave's three most-used entrances. The shield door further enhances this area's strategic potential. Above the Ice Cave's main entrance spawns a Brute Shot (top), as well as a Spiker to the west and a Mauler to the east. Players have several points of entrance and exit, but the tight quarters of this cave make maneuvering quite difficult. An oft seen tactic on this map is to hide on the other side of a shield door with the Shotgun or Mauler, and kill players as they pass through.

Trivia

 * This was the first Halo 3 Multiplayer level ever shown to the public.
 * This is one out of two multiplayer maps in Halo 3 which take place on a Covenant-controlled territory.
 * Snowbound is also the title of a 1994 movie, starring Neil Patrick Harris and Kelli Williams.
 * There are several automated turrets positioned along the outside of the map which will shoot at any players who go beyond the boundaries of the map.
 * When you venture outside the boundaries a siren wails as a warning to go back before the turrets kill you.
 * In the Beta you could use a Bubble Shield to defend yourself from the stationary AI turrets, allowing you to travel further out of the map than usual. This has been fixed in the final version of the game though.
 * A tactic introduced after the Beta is for the leader to rush out with the oddball and be killed by the turrets, leaving the ball unattainable, thus allowing the team or player that has more time holding the ball to win before the round ends.
 * Like Sandtrap players may leave footprints in the snow (which could be tracked) for a few seconds before fading away. This is helpful when opponents are in Active Camo.
 * Even if you are invulnerable, the Guardian boundary turrets will still be able to kill you.
 * In the sky, the visible planet has a Marathon symbol on it.
 * The spheres in both bases appear to be vehicles since there are seats inside them.
 * In the Active Camo tunnel there is a Canadian $1 coin buried in the snow beneath the Active Camo.
 * In Master Chief Sucks at Halo, a popular Machinima series, Snowbound is the Chief's least favorite map.

Strategies

 * After swapping for the Spartan Laser when spawning in Team Slayer, if your team doesn't plan on using the Ghost, a good tactic would be to wait for an enemy to get in it, eliminating the Ghost threat, that enemy, and possibly the Overshield Threat.
 * Even though the outside is good for sniping, the Beam Rifle is more commonly used inside for no-scoping and double shots, which is usually rather effective.
 * The rocks lined up near the Ghost spawn is normally a less risky way up top when traveling from base to base.
 * The ceilings inside the bases are in fact transparent, enabling you to see potential assailants above you.
 * The Needler can be very useful on this map.
 * The Maulers on the Tundra side of the map can prove very useful if you intend to patrol the ice caves.
 * In the ice caves a Deployable Cover is useful in team games, as you can throw it out when an enemy is trying to get through.
