Danger Canyon

Danger Canyon is a multiplayer map originally exclusive to Halo: Combat Evolved for PC and Halo Mac. It is included in The Master Chief Collection. The level is somewhat similar to the Halo and The Silent Cartographer levels in singleplayer campaign of Halo: Combat Evolved.

Layout
Danger Canyon features a long, narrow, and winding canyon with an alternate passageway leading to a second level in the center of the canyon. It is a large level and teams can get stuck fighting across the second-level canyon area for extended periods of time. The tunnels going through the cliffs will lead to your opponent's base and a cliff.

Strategies

 * There are 6 ways in and out of the tunnel system. Learning the tunnels' anatomy is highly recommended, and in CTF, it can lead to getting out of the enemy base with the flag quickly and efficiently.
 * The map has a few critical capture points:
 * From both passes, a tunnel can be taken that leads to a central room. This room is used to access the bridges. If a team can gain control of it, they can prevent the enemy from passing. This wreaks havoc on the enemy, leaving them no way to escape or advance.
 * The far side of the bridges can be key to a teams success. A sniper rifle, pistol, fragmentation grenades and an overshield spawn here. A skilled sniper can pin enemies on foot in the tunnels. This sniper can also pick off slower vehicles that may pass, like a Scorpion tank or an unsuspecting Warthog. Additional teammates can go through the tunnels, across the bridges, and through the teleporters to get to vehicles that may be waiting there.
 * Coordinated vehicle attacks can be very effective in CTF. Scorpions and Warthogs can be used to pin the enemy down, while a Ghost user takes the flag back to base.
 * Another tactic is to collect both the Fuel Rod Gun and Rocket Launcher in the tunnel system and then raid the enemy base.
 * Similar to Infinity, Danger Canyon was designed specifically so that coordinated team attacks are a necessity for success.
 * The passageway leading to the second floor is large enough to drive a Warthog through and up to the overlooking platform, giving a good firing or sniping position.
 * In CTF games, steal the flag going up inside the premises with a soldier escorting you with an M7057 flamethrower for fighting in small places.
 * To prevent your enemies from stealing your flag in a CTF game, take a Ghost or a Warthog and park on top of the flag facing the entrance of their base to destroy invaders quickly.
 * To invade the enemy base quickly and flip vehicles, use a Fuel Rod Gun, then use a Warthog to escape quickly.
 * One of the best strategies for CTF is to leave two people to guard the base, preferably with either the Scorpion or Rocket Hogs, and send everyone else straight through the tunnels. Going across the main section of the map is never advised.
 * In Team Slayer, the most important place on the map is the ridge across the middle bridges. The Sniper Rifles are invaluable and overmatch any other infantry weapon (including fuel rods and rocket launchers, because of the distance between the ridge and enemies). The position protects from most vehicles, the only possible threat being the Scorpion's blast radius. However, any skilled sniper can snipe a Scorpion driver with relative ease.

Trivia

 * Wall hacking can be performed in Danger Canyon, given that there is at least one Ghost or Warthog, and friendly fire turned off. Start a new game on Danger Canyon and get into either vehicle. Get a teammate to get in front of the wall closest to your enemy's base and ram them through the cliff wall. Sometimes this may fail, leading to your teammate falling through the map. If it does work, you will be at the opposing team's base.
 * It is possible to get a Ghost to the other side of the canyon top.
 * Many players will take Warthogs and Ghosts through the tunnels and camp on the platform in the Canyon's center; it is possible to get a Ghost across one of the bridges leading to the ledge with the teleporter with precise timing.
 * You can survive the fall off the platform in the center if you have an overshield and land on one of the ramps.
