In The Evasion you once again take control of Adrian Shephard set shortly after the nuclear bomb that devastated the Black Mesa Research Facility. The Evasion is a small map pack for Half-Life. Development started in July 2011 and thus far is going slow but surely. Despite some hiatuses I plan on finishing it this year.
I forgot to put up an news article for the actual release since I'm an idiot.

People who have already played it can ignore this belated news message.
The Evasion is a small 6-level singleplayer modification for Half-Life. Set shortly after the devastating ending of Opposing Force you once again take control of Adrian Shephard while trying to figure out a way to get back to Earth.
Note that Opposing Force is not required for you to play it and as such Half-Life is the only thing you need to run it.
