In Counter-Strike: Source, the environment dynamically changes between rounds. For example, in one round a window may be open but in the next one it will be closed. Due to this, Havana is a very difficult, if not impossible map to master, and as such is one of the least played maps in the game.
The upstairs rooms appear to be color coded as the green rooms face the courtyard while the yellow rooms lead to the atrium.
Graffiti depicting the famous Communist revolutionary Che Guevara can be seen on several walls.
In Counter-Strike: Source, bots may have navigation issues when the doors or windows at the apartments have been closed (off). They may attempt to access through these areas and will get stuck, thus resulting them in wasting time.
