Thievery

Fans of the PC series Thief might also be interested in this mod from the same development team. It takes the Thief universe and uses UT2004 to create a multiplayer version.

This mod for Unreal Tournament was born out of a desire to see the Looking Glass Studios' classic game, Thief, made multiplayer. Thievery UT pits a team of sneaky thieves against a team of tough guards, featuring interactive environments and an unprecedented use of dynamic lighting in a multiplayer game.
Both teams have unique equipment at their disposal, which they must use to their advantage. Thieves will use water arrows to put out torches and flood the maps into darkness, so they may pass unseen, or take out any guard foolish enough to walk in the shadows. Guards, heavily equipped and armoured, must protect the loot and kill any trespassers. Thievery features numerous detailed, atmospheric levels, with considerable background to each, making it interesting to play both solo and multiplayer.

NightBlade

http://www.night-blade.com/This is another stealth game and will initially be an updated version of Thievery, this time running on Unreal Tournament 3.

A guild of cunning thieves sneaks their way into an opulent mansion, filled with the riches that only generations of power can acquire. The mansion's private guard patrol within, seeking out intruders and relentlessly hunting down those that their efforts reveal. Every shadow is a potential hiding spot, every noise might be a clue to the presence of thieves. Every second lost can mean the difference between victory and defeat.



Nightblade is a total conversion for Unreal Tournament 3 featuring stealth-based gameplay. A team of thieves must use stealth and skill to obtain loot and escape, while a team of well-armed guards must protect the loot and hunt down the thieves. Both teams will have a variety of equipment at their disposal to aid in their task. Thieves will use water arrows to put out sources of light, extending the darkness within which they can hide. Guards in turn will use flares to relight torches and search the shadows for thieves.

The initial plan for Nightblade is an updated version of ThieveryUT's Thieves vs Guards gametype, making use of resources from Thievery, Nightblade when it was targeted at UT2004, and over time new resources generated specifically for UT3. We will be experimenting with a number of gameplay changes and improvements as well.

This game is still in early alpha testing, but the alpha builds are already fully playable, so if you are interested take a look at the official site and download and play around with the current alpha build.
