El steam te recibe con esta noticia:
The next big update coming to our multiplayer games will include two completely new maps for Day of Defeat: Source, named Colmar and Jagd. (Long-time Day of Defeat players will recognize the name Jagd, but the name is really all the new map shares with its predecessor.) Both maps will have slightly differing takes on a new gameplay style we're calling "Detonation". Both will be released on the 28th of June, along with other updates to the game itself
Es decir que el 28 de junio tendremos los nuevos mapas Colmar y Jagd,muy cambiado con respecto al de 1.3, con un nuevo tipo de juego "Detonation" tipo CoD y cs
