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:...
Probably one of the most memorable mod I've ever played to HL2. A game aiming for suspense and reaction for the players while adding adrenaline kicks when playing as Subject 617 or as IRIS. Highly celebrated and loved mod at LAN events and with friends. First time me and friends got this mod on a LAN part we played 14 hours straight which says quite alot to me, considering how low attention-span some mods have or even AAA games.
The weapons are somewhat balanced and you also have interesting equipments like sensors or laserdot. Also playing as Subject 617 is great fun using the voice commands to scare newbies to the mod and trying to seperate the groups.
I highly recommend this mod,also my other friends who have enjoyed and loved this mod.
