Dust II - Is - Love

At bombsite A in Counter-Strike, you can find graffiti saying "Goose". This is a reference to Minh Le "Gooseman", the co-creator of Counter-Strike.
In Counter-Strike 1.6, there are two hidden messages in the map. In the Counter-Terrorist Spawn Zone, there is a note from Dave Johnston who thanks everyone in the making of Dust2. Elsewhere, there is another message that dedicates this map for Justin DeJong.
In Counter-Strike: Source, there is a text on the wall in Bombsite B in Farsi which says "فریمن اینجا بود". It means "Freeman was here" as a reference to Gordon Freeman, the main protagonist of the Half-Life series.
Dust2 is the most popular map in the Counter-Strike series and can be considered the most popular and iconic bomb defusal map ever created. It is chosen by many Counter-Strike tournaments as well.
In Global Offensive, the boxes in both bomb sites are adorned with the arabic text, "الفواكه" (al-fawakih), which means fruit.
There is also "سي اس سوس", pronounced as "Si As Sos", similar to the pronunciation of "CS: Source".
The burning car wreck in the Terrorist Spawn Zone and A Long in Global Offensive does not inflict any damage, even if a player is within contact of the fire.
