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.

nvm i got the sides now, humans with the power if vamps or lycans, love the superhuman modes, theres only one sever max players of 8 and its empty 24/7 im the only one who joins but im it.

im known as Reaper ingame. good thing no bots in here, they would have ruined it, but its a good thought knowing that server is empty.

I'm going to try and talk to Neil and co. to see if we can get any of the source files for this mod released. It's not a bad mod, but it needs a little more "oomph". The teams are slightly unbalancced, too. The Vampires have more variety in weapons while two of the Lycan classes are identical save the skin.

Hopefully if the code is released someone will pick this up and improve it.

And no, this mod does not suck one bit! It's actually quite fun even with a small number of players and in a fairly laggy server. The funniest and dumbest things can happen in this mod, which makes it so interesting. But sure, it needs a few minor tweaks, a few new weapons or maybe even a map or two. Even one or two more servers and players would help boost the popularity of this mod. (in my humble opinion)

I think this mod need an improve , rate of fire for SMG weapons should be way faster and they should carry a right ammount of bullets.Theres no way that MP5k can carry 50 9mm bullets per mag , especially when it has the small mag as in this game.Neither it could have 15 or 30 bullets per mag.Oh , but in the movie Kate also fires 100 bullet out of her automatic pistol hehe ;)

There should better gameplay mode than this "hybrid" thing.Maybe you should have to capture a blood examples instead , because then theres not messing with that hybrid to make him follow you.He gets always stucked somewhere.

I got some gameplay ideas : 1. Infiltrate vampire mansion and kill someone very important.
2.Kill vampire elder , and suck her/him out of blood , then take the example to the lab.
3.Attack and blow up Lycans lab

Also , giving players better "special ability" than just "jumping half a meter higher than usually.In the movie they jump sometimes over 2 meters high.Why not in a game ?

And last , there should be Lycans , that actually can trasform into wolf form and run faster , jump higher than normal werewolf player.Older and more powerful Lycans could do it by the will , so theres one extra special ability.

And also , levels need to be improved , if i had source files i would make them bigger.I quess i have to start all over again and make my own map then :P

Its sad noone ever made any decent game based on this movie.Its like the fact that theres lots of "Rambo style" games , but no game actually based on Rambo movie :P

I know this sounds like a whining and you probobly will answer "then do it urself" , but i cant do anything besides mapping :( Sorry... Its just that theres no fps that allows you to run and jump from one rooftop to another.(sv_gravity wont count , it makes you just float , not jump in cool ways)

Its pretty good mod otherway.I love the regeneration ability.Its almost nowhere to be seen in games :(
Jet one of my favorite elements ;)

your not suppost to spawn max ammo first of all and 2nd your right, the lycans are like all same weapons

vampires have the ++ over here cause on the D maps they can just roof jump and stun the lycans plus the fact superhuman abilty is only just the sprint speeds. anyways the leader class has a whip, the master death dealer has her own personal pistol and yea. this mod is about the hybrids cause thats what they wanted it to, it makes either side invicable, but agreed, they are a bit slow and always stuck somewhere when u go to fast. like uw_train. i had to walk with him instead of riding the train cause he can't run faster then hes programmed speed. LOL. other then that theres only 1 server and its empty 24/7.
