Underworld Bloodline is a team-based multiplayer Half-Life mod based on the Sony action movie "Underworld". Rival clans of Vampires and Lycans (werewolves) fight each other while trying to secure a human that hides the power to make them invincible. The gameplay can be described as a mix between Hostage Rescue and Capture the Flag, but the maps are a lot larger and more complex, offering opportunities for a wide range of strategies, such as snipering from inside buildings or taking shortcuts by jumping between rooftops

When night falls, the battle begins. Unbeknownst to the human world, a centuries-old feud between warring Vampire and Lycan (werewolf) clans is escalating to a bloody and brutal climax. Armed with an arsenal of deadly weapons both ancient and modern, these mortal enemies are unrelenting in their quest to wipe each other from the face of the earth. You must choose on which side you will fight. Will you align yourself with the lithe and elegant Vampires, or the brutally powerful Lycans? Prowling the dark city streets and subway tunnels, you are compelled to destroy your ancient enemies while searching for The Hybrid -- a human with the power to make your people invincible.

Underworld Bloodline features four maps:

UW_CITY (hunter style):
A teamplay game similar to Capture the Flag, but using a live target instead of a flag. Your goal is to find and capture the Hybrids and return them safely to a prison cell at your home base, battling any enemy fighters in your path. To locate and secure a Hybrid, look for the one in the bar or restaurant in the city. Press 'E' to make him follow you, press 'E' again to make him stop. Once you get him inside the cell, activate the prison cell button to capture him. Once captured, the Hybrids will regenerate and win points for your team. Each team scores 1 point for every enemy kill, 10 points for a Hybrid capture, but loses 5 points if they kill the Hybrid by accident. The team with the most points at the end of the match wins.

UW_TRAIN (escort style):
The Lycans have brought the Hybrid close to the city limits, but now they must move him beyond the gates. The Lycans must lead the Hybrid through a Vampire infested city. Hidden rooms, water and a moving train add to the complexity of the mission.

UW_FACTORY (assault style):
The Vampires have imprisoned the Hybrid deep within a large factory complex. The Lycans must penetrate the Vampires defenses in order to find the Hybrid and help him escape. There are multiple objetives that must be conquered progressively before reaching the final escape area.

UW_FORTRESS (fortress style):
A classic capture-the-flag game, the goal for each team is to rescue the hybrid from the enemy's fortress tower and bring himback to your own base. This map was adapted from the acclaimed TFC map "Vidars Nifleim 2" and converted into a darker, more sinister look, set at late twilight in an icy mountain setting.

I'd love to play this game again with others. When it first came out I played it until all the players disappeared. The spiders and mines I thought were pretty hilarious. It was cool seeing the Lycans being able to transform into werewolves, and I remember that the M16 was pretty deadly if you canceled a single shot into a three round burst.

In honor of the upcoming 10th anniversary of this mod and movie, I scrounged up the old sony website (taken down) and put it on my website so people may bask in a time that once was! I changed some of the links so they aren't dead links though, and take you to this moddb page.
