Hidden Source mod for Half-Life 2

In "The Hidden", players choose the role of either a near invisible killer, Subject 617, or one member of an Intercept squad who have to capture him, I.R.I.S. In the simple but challenging gameplay of an 'one against all'? mode, Subject 617 creeps/sneaks through the maps armed only with a knife and three pipe bombs. The IRIS team carry a selection of weaponry, fully customisable at round start, from F2000 assault rifles through to shotguns or sub machine guns as well as a pistol as a secondary weapon.

However, they can hardly see Subject 617 as, just like the 'Predator', only the outline of his silhouette is visible. On top of that the Hidden also moves a little faster and has many abilites such as pouncing, wall grabbing, corpse pinning and the fatal pigsticker attack. Therefore co-operation is necessary for I.R.I.S. if they wish to prevail (if they dont want to become the prey/victim themselves).

This leads to an outstanding gaming experience on public servers: The I.R.I.S team creep/sneak through the corridors, back to back & covering each other whilst Subject 617 lurks in dark corners choosing his time to attack. The player who finally kills the Hidden takes over the role & from then on he can roam like a ghost through the corridors.

Background

In the early 1950's human genetics experimentation was taking its first, tentative, steps. Amongst many other black projects, a team of British scientists working at a Infinitum Research experimental station stumbled across some remarkable phenomenon involving DNA manipulation. This led to deeper research with dangerously unpredictable results, often leading to human patients losing their lives in irresponsible and immoral experiments.

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. The British team were hoping to unravel the possibilities of light manipulation to create the perfect covert military agent. 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. The subject escaped captivity, killing anyone that got in its way, the I.R.I.S (Infinitum Research Intercept Squad) team have been deployed to return the subject to a maximum security Infinitum Research facility for further study and dissection. The entire project was considered a failure, all funding ceased and development was discontinued. All records and traces of the experiments were destroyed. Infinitum Research denies all knowledge of any form of human DNA manipulation but are more than happy to comment on the possibilities of cloning human organs inside suitable animal donors. It is believed that these organ cloning experiments form the main cover for their human genetic manipulation experimentation.

As the I.R.I.S team close their net around it, subject 617, known as The Hidden must turn the tables becoming the hunter instead of the hunted!
