Defuse

Bomb Defusal is the most popular gamemode in the Counter-Strike series.

For terrorists to win, they must:
 * Plant the bomb, and ensure that counter-terrorists don't defuse it, or
 * Kill all of the enemy team.

For counter-terrorists to win, they must:
 * Prevent the bomb from being planted for the entire round, or
 * Defuse the bomb if it is planted, or
 * Kill all of the enemy team (unless the bomb has been planted, in which case it must be defused).

The bomb has 40 seconds until it detonates after being planted. If both teams have at least one alive player at the end of the round and the bomb has not detonated, counter-terrorists are given the win

Spawns
Spawn players with and. The exact location players spawn in can sometimes severely impact gameplay. Players tend to take whatever route is closest to them, due to the amount of time spent walking to a meeting point being very crucial. In CSGO, spawnpoints can be given a priority to mark which are more or less desirable. Since servers can go up to 32 players, each team should have 16 spawns, otherwise players will spawn inside other players.

To create the zones for buying weapons and equipment, create a brush around the spawn points for each team, select the brush, and press to tie it to an entity. Change the entity class to.

Bomb sites
To make a bomb site, create a brush tied to. A bombsite being A or B is determined by the order the  entities are created in.

Typically, bomb sites are placed closer to Counter-Terrorists so they can get into a defensive position without Terrorists planting the bomb. Each site should have at least two entrances; most cover is set up so that you can watch one entrance while being covered from the other.

Miscellaneous
Though your Bomb Defusal map will work correctly with any prefix (or with none at all), using the  prefix allows the game to correctly identify the type of map as a bomb scenario during loading screens.
