Underhell is an Half Life 2 Modification that will be distributed in Episodic releases.
It is a community project that gathers content with permission from various different authors.
The mod has been in development since 2005, and has evolved many times before reaching a stable concept.
In Underhell, you play as Jake Hawkfield, a Special Weapons and Tactics operative who recently married and moved in with his beloved wife.
But soon after those happy events, his beloved wife dies under mysterious circumstances, leaving only clues that suggest she committed suicide.
Jake falls apart, and only his best friend, mentor, and boss Frank is there to help him get over his grief.
The mod begins with a wake up call from Frank ordering Jake to come down to the station.
An armed group of elite soldiers have taken control of a hospital and all its personnel.
But Jake will soon realize that this is not a common hostage situation…
