Half-Life 2 Hidden: Source mod

In the early 1950's human genetics experimentation was taking its first, a team of British scientists working at a Infinitum Research experimental station stumbled across some remarkable phenomenon involving DNA manipulation. Time passed on, and by the mid 1990's the failure rate of the experiments had been reduced from 75% to a mere 15%, enough for Infinitum to move onto the next stage, Biological Light Refraction. Early into the new millennium, due to a gross miscalculation, a series of tests on Subject 617 led to a massive synaptic trauma leaving the patient with multiple genetic anomalies.

The subject was left in constant pain and with unstable DNA. It escaped captivity, killing anyone that got in its way. The I.R.I.S (Infinitum Research Intercept Squad) team has been deployed to return the subject to a maximum security Infinitum Research facility for further study and dissection. As I.R.I. team closes its net, subject 617, known as "The Hidden," must turn the tables on the team, becoming the hunter instead of the hunted!

This release of the mod Hidden: Source includes 5 maps and two playable classes. The players must hunt down subject 617, a hidden player with enchanced abilities. In turn, 617 must prey on the other players.
