The third week of id id software's campaign "6 Maps in 6 Week" brings us another ctf map. Here is official release announcement that covers Bloodlusts background and information about the next map:
In 1999, id Software contracted two young developers, Michael "Casey" Goodhead and Dave "Zoid" Kirsch (known collectively as "Threewave" to create 3 Capture the Flag arenas for QUAKE III Arena. The first in this 3-pack was called Bloodlust - and now the source from which we bring you our week 3 release. In revisiting this map over the last couple of months, the team here decided to make some renovations before releasing it in QUAKE LIVE, and we're very happy with the additions, changes, and polish we've been able to contribute. Bloodlust is perfectly suited for 8 to 10 players and rewards teamwork.

Our long-time friend Casey continues to bring his talents to the game industry as the Game Design Director at Threewave Software.

Although we've now released back-to-back CTF arenas, next week's release will certainly quench the thirst of our Duelers. Stay tuned.
