Black Mesa: Sideline is a small Half-Life singleplayer mission. It contains 2 maps and is fully compatible with HL-Steam and HL-Won.


Extract the zipped package to your Half-Life folder in Steam or i.e. “..SierraHalf-Life..” in case you are using the won-version of HL. That’s it, have fun.


I created Black Mesa: Sideline to participate in a little Half-Life mappack project that was arranged by the german Half-life mapping community in June 2007. In the end I wasn't able to finish my part of the project so I threw together what I had and released it without any story elements.

It turned out to be moderately successful and I am still very satisfied with the quality I accomplished back then.

  1. When exactly will the Air jordan 12 French Blue release? One of the biggest releases of 2016 to date has been pushed back and rescheduled quite a few times over the past few weeks, and we’re still a bit unclear when this retro will arrive. While Jordan Brand confirmed that the release would be pushed even further back to April 9th along with a number of other upcoming pairs, major retail outlets like Foot Locker and smaller shops like Rock City Kicks are all reporting that this upcoming Saturday, April 2nd will play host to the covetable release.
