There’s a download limitation with the host where I have my server. Any map over 64Mb is not downloading and the players end up being kicked out.
To solve this problem I am uploading all maps here.
You must save the maps on C:\Program Files (x86)\Steam\SteamApps\common\Half-Life 2 Deathmatch\hl2mp\download\maps.
If your install in on a different drive, replace the C: for that drive.
I’ll be adding new maps as time goes on, but I’ll keep adding them to the link above so anyone can download them.
