Map prefixes and suffixes

Common traditional naming conventions for maps for some GoldSource and Source games use a small prefix (often two or three letters) followed by an underscore at the beginning of the map name. For example, de_dust, where "de_" is the prefix and "dust" is the map name. In addition, some custom maps are marked with unofficial prefixes, either to denote its nature or to brand it.

Todo: Add descriptions and prefix names for those who do not have any.

Team Fortress 2

Prefix	Map Type	Description
Official
arena	Arena	Added with the August 19, 2008 update. Kill the entire enemy team, or capture the point once it unlocks.
cp	Control Points	Original Shipping Map Type. Two main variants. One ("5CP") gives each team two capture points, with a third one in the center. These points can be captured by standing on them for a certain amount of time if your team controls all points closer to your spawn; the game is won when one team captures all five points. The second variant ("Attack/Defend") starts out with the BLU team locked in spawn and RED team controlling all points. After a brief setup period, BLU must capture all the points before time runs out, or else RED wins.
ctf	Capture the Flag	Original Shipping Map Type. Grab the enemy flag from the base, bring it back to your base, repeat as necessary (usually twice). Capturing a flag rewards your entire team with a brief damage boost.
pl	Payload	Added with the April 29, 2008 update. Like the aforementioned "Attack/Defend" variant of Control Points, except rather than capturing control points, the BLU team must push a cart along a track. Essentially an escort mode.
tc	Territorial Control	Original Shipping Map Type. A series of small, semi-random "stages" with one control point owned by each side. Capturing the enemy point ends the stage and pushes them back, allowing you to attack their next point. A team wins when they capture all points on a map. There's only one official TC map, tc_hydro.
plr	Payload Race	Added with the May 21, 2009 update. Like Payload, except both teams have a cart to push, and instead of one team owning the points at the start, each team has a different set of points they must capture.
koth	King of the Hill	Added with the August 13, 2009 update. Each team has a timer that starts counting down when they capture the single control point. The other team can stop this timer by taking the point from them, which starts their own timer in turn. A team wins when their timer reaches 0.
tr	Training	Added with the Mac update. For training maps.
sd	Special Delivery	Added with the Pyromania update. Like Capture the Flag, except there's only one "flag" and one destination, both of which are neutral.
mvm	Mann vs Machine	Added with the MVM update. A player-versus-environment mode where a team must cooperate to hold off sucessive hordes of robots.
rd	Robot Destruction	Not yet officially released. Like Capture the Flag, except instead of bringing back a flag, you must destroy robots in their base and pick up the "cores" they drop. A team wins when they pick up enough cores, but the other team can win by sneaking into their base and stealing from their core vault.
pd	Player Destruction	Added in the Invasion community update. The two teams duel each other, gaining pickups upon killing enemies. At regular intervals, a deposit point will temporarily become available where either team can turn their pickups in. A team wins after depositing a certain number of pickups.
pass	PASS Time	Added with the Meet Your Match update. A deadly game of soccer-hockey-basketball.

Maps may be played as cp, ctf, dm, arena, or skill. (skill-surf simply being a challenging map that involves no deathmatch).
ph	Prophunt	Red team is turned into various props, and given an amount of time to hide around the map. Blue team must find them all before the round ends. Usually when there is one prop left alive, they are given their weapons back and Blue team is coated with Jarate. To be used with the Prophunt (Hide and Seek) mod.
