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.

Oops I shouldve added this, but another really annoying thing is when you bust your *** to bring a hybrid to your base alive, then when you lead it into the capture room, a teammate presses the button and captures your hybrid and gets the points, while you lose a life. People were mentioning in game it's being worked on where you can actually turn into a werewolf, that would be cool :D

but anyway the hybrid capturing is extremely annoying, and considering that's the basis of the game I really think it should be improved.

Eh I thought it was okay, but the hybrids kept getting stuck on everything, it was hard to distinguish friends from enemies, and the weapons were kind of boring. But the playing was fairly smooth even though, boring. . .
Maybe if there was more to do. . .

i like it...it was cool that it's dark, but the maps have just the right lighting, so it wasn't too dark. the maps are large and offer lots of variety for potential combat. i thought the weapons were good although somewhat generic in type. the player models looked great but yeah, there isn't a whole lot of difference between the lycans and vampires here. even though it's nothing groundbreaking, i give it a 9 because it's a real quality mod that's fun to play. also, it's nice that i can play this mod smoothly even on my crappy machine...:)

gee, i thought i already wrote something here

I thought it just wasnt very good, it didnt have a lot of weapon variety and its hard to tell the difference between the classes on the one side.
But it does have OK gameplay so I award it a 6/10.
Hopefully they will patch it.
