Are you still waiting to receive access to the CS:GO beta? Well we have something to tide you over until then.
DARKLY Gaming Network has just created a CS:S server with a map cycle of custom ported CS:GO maps.
The current mapcycle is: de_dust2_csgo, de_nuke_csgo, de_inferno_csgo, de_train_csgo, and de_dust_csgo. Download links for each map are listed below, or you can download the full csgo map bundle. The ported CSGO maps are installed the same way as you would install a normal CS:S map:
*drive*:\Program Files\Steam\steamapps\*username*\counter-strike source\cstrike\maps\
