Creating a Bomb Defusal Map
Bomb Defusal scenarios are played in the Classic Competitive and Casual gamemodes. Players earn money by winning rounds, getting kills, and by planting or defusing the bomb. They can purchase weapons and equipment at the beginning of each round.
Bomb Defusal maps require spawn points and buy zones for each team, and at least one bomb site, but usually 2- A and B.
Additionally, Bomb Defusal maps use the
de_ prefix in their file name- for example, Dust 2 is named
The Casual game mode is 10 vs. 10 on official servers, but it is a good idea to include 16 spawn points for each team, to work smoothly with 32 player servers.
In Classic Competitive, there are only 5 players on each team. Timings to bomb sites are very important in defuse maps, so you are able to choose certain spawn points to be used before others.
To change the spawn priority, select the spawn point and open the entity properties. Find the
Spawn Priority property, and change the number to be higher or lower. Lower numbered spawn points will be picked first.
For example, you might have 5 spawn points set to priority 0, and set the remaining spawn points to priority 1. The 5 spawns set to 0 will be the only spawn points used in Classic Competitive matches.
Create a brush around the spawn points for each team, and texture it with the
tools/toolstrigger texture. Now select the brush, and press + to tie it to an entity. Change the entity class to func_buyzone. Open the entity properties, and set the
Team Number property- this decides which teams are allowed to use the buy zone.
Make a brush textured with
tools/toolstrigger, and with it selected, press + and change the entity to func_bomb_target.
Heist Mode bomb Targetis an unused value and should be ignored.
The bombsites are assigned as A and B in the order the func_bomb_target entities were created. Though the official Bomb Defusal maps have two bomb sites, the game will work correctly with just one, though this is only recommended for a map in testing stages.
Bomb sites are placed close Counter-Terrorists so that CTs can get into a defensive position without Terrorists planting the bomb. Each site should require two entrances; most cover is set up so that you can watch one entrance while being covered from the other.
Though your Bomb Defusal map will work correctly with any prefix (or with none at all), using the
de_ prefix allows the game to correctly identity the type of map as a 'Bomb Scenario Mission' during loading screens, if your mapname.txt is configured correctly.
For example, Dust 2 uses the file name
