Evacuation tells the story of a rebel who crashed his helicopter in the forest. The protagonist barely survived, and now he has to get out of the forest, which is being explored by the forces of the Alliance.
The developers of the unofficial add-on reported that players will find locations atypical for Half-Life 2, puzzles and battles with Alliance soldiers, raiders and zombies in it.
In Evacuation, players will, among other things, have to wield an ax, as well as use a walkie-talkie, on which it will be possible to talk with allies.
On the passage of the DLC, on average, it takes about an hour.
The add-on is available for download on Steam for free.
