Favela

Favela is a multiplayer map in Call of Duty: Modern Warfare 2. It is a multi-tiered map set in the slums of Rio de Janeiro, featuring fast paced and close quarters battles. It has many tall buildings for snipers and alleys for close quarters. Much of the map is built vertically with plenty of space around the rooftops and two-story buildings. This map can accommodate many different styles of play and gametypes.

Description
This is an extremely tricky map because enemies can be found coming from almost any direction. The fact that most buildings feature two stories make keeping track of enemies very difficult. Getting the high ground on this map may give players more range, but they need to keep their eyes open in all directions and altitudes since there is seldom any solid cover on the higher levels. The Commando perk or a Tactical Knife can be very useful on this map, as players will frequently be running head-on into enemies. Commando Pro's fall damage resistance can be useful too; on the roofs, sometimes the best way to get out of an enemy's sights (or to get the drop on him) is to drop off a building. Also, falling too far from buildings will cause severe injury or death unless using the Commando Pro perk.

Controlling the high ground will help win a match, though every building has more than one way of reaching the roof. Players can jump across most roofs, to help with the battle.

Although this map is fairly large, close quarter encounters are frequent, especially near buildings that lead to rooftops.

The ditch on the upper level (The flag spawn for Task Force 141) is often overlooked, as most action takes place down at the lower level. This area can be a useful defensive feature for objective-based games or for ambushes. Hiding in the ditch, and waiting till the signal that an enemy is taking the flag, can be a very effective ambush.

Tactics
The Favela is a challenging place to fight in, as the map contains narrow alleyways, claustrophobic rooms and multiple stories from which players can shoot. Running into the open can result in being targeted from almost any direction. However, going into buildings can result in players with shotguns or SMGs waiting in ambush. In addition, the sides of the map are clear, straight and covered by easily defended positions, making it also relatively dangerous to move around the edges. In some gametypes, teams can often get bogged down in bloody fighting on the road because of this reason. Those who seek higher ground can easily flank and travel the map much faster. However they become easy targets if there is no cover from air support or enemies on the rooftops.

Light automatic weapons are recommended for this map. Because of the prevalence of close quarters combat, assault rifles and submachine guns are preferable. Shotguns, especially the AA-12 for its automatic fire, are also highly effective at sweeping alleyways and clearing rooms. A class with Marathon and/or Lightweight can be very effective in getting around the map quickly, and for surprising enemies.

A good tip for snipers is to not always seek the high ground, but to look for wide open areas where a runner is an easy target, and make sure that the location one is sniping from is either hard to get to or has only one entrance to prevent embarrassing knife deaths. A neat little spot is on the roof next to the building with the stone cover, as the roof is a hard spot to target without one noticing. The only problem with this spot is getting killed from behind, but that is not much of a problem because the TF141 spawn point is on the other side, giving the sniper an advantage when they run outside.

This map features many effective places to place claymores, especially in tight alleyways and corners found in the center of the map. Claymores can be a very effective way to defend flags B and C, and to a lesser extent A, in Domination gametypes.

In Domination, a good place to defend A, (Task Force 141 spawn), is behind the flag, players can see a small trench with a small bridge of boards in the middle. Players can sit in here and have an almost complete view of the entrances. When a few people start to get killed, enemies will start taking counter-measures against the player, such as throwing grenades into the trench, or flanking the player. Because of this the player needs to be aware of his surroundings at all times while in the trench, if fighting against a player in the trench, players should make sure take a good look around the A flag, as there may be a player, or a group, waiting to take them out when they get near, or start capturing A. Also with Lightweight and Marathon, if the player decides to attack while on the TF141, a player can run from point A to point C before the enemy captures it and kill everyone with a semtex. Also, it is possible to capture B from inside the ice cream shop nearby.

If using a Harrier Airstrike, a good place to call it in is the large courtyard (the large area between B and C), it can easily gun people down due to a lack of cover for players, but with buildings adding to it's protection making it hard to shoot down.
