Underground is a Half-Life singleplayer mission. It contains 17 maps and is fully compatible with HL-Steam and HL-Won. This download includes the gametitles in english and german. The estimated time for playing through it, will be something between 30 and 60 minutes.
Looks very nice. You should go source.
