Caliber is a mod that started 2 years ago when a group of guys wanted to make a truly unique HL2 mod. After years of hard work, setbacks and the occasional miraculous success, the team has finally come within weeks to a closed beta. The mod is based in a science-fiction setting, whereupon 3 warring vampire clans, the Order, the Vamin and the Absentis, each fighting for control of the vampire underground. Key gameplay features include:

- An innovative resource system, where killing enemy troops and capturing vital control points allows the player to gain access to new equipment.

- A hierarchy of character ranks, allowing a captain to take control of his team and lead a squad through the game to victory.

- 3 distinct character classes for the 3 sides, each boasting its own form of combat and natural skills.

- Dark, mysterious maps with superb lighting effects, dangerous chokepoints, excellent ambiance and the constant fear of the unknown.

- 3 distinct factions: The Order, the faction made up of holy men trying to expell vampires from the world; The Vamin, a technologically superior race of vampires utilizing superior ranged weaponry and advanced suits of armor; The Absentis, an exclusively melee faction that utilizes stealth, speed and supernatural abilities to vanquish its enemies.

Watch in the following months as Caliber is released to the public. And remember: You have been warned.
