A Hidden: Source Beta Group

Hunt down an invisible enemy.

The Infinitum Research Intercept Squad (I.R.I.S.) is on the hunt for a fugitive, the subject of a secret genetic experiment, who is known only as Subject 617.

The Good News: The IRIS team is well trained, well armed and co-ordinated.

The Bad News: The genetic manipulation has given Subject 617 enhanced speed, mobility and incredible strength - he can pounce like a tiger, cling to any surface and is known to pin victims up for feeding. Worst of all, the experiments have rendered him nearly invisible to the human eye. This is why he is simply known as ... The Hidden.

We're a group of casual Hidden players.

This is an open group, welcoming all members of The Hidden community. We invite all players, of every skill level, to join this group and socialize with other members of our rather small playerbase.

The Hidden is a Source Engine mod in which one player is invisible with a knife, and the other players must kill him before he kills them. The Hidden can leap meters above the ground, throw pipe-bombs, and stick to walls. The IRIS are the team sent in to kill him, using high-tech equipment and their quick impulses to best their opponent.
