The Lambda Arena page has a new version 1.09 beta of this deathmatch Half-Life modification that offers the last-man-standing teamplay of Rocket Arena for both one-on-one, and team matches. The new release offers heavily altered weapons ("more realistic...the 'beefed-up' stuff didn't really work)," a "unique weapons system" (you now choose one weapon from each of four categories--handguns, assault, experimental, explosive), along with fixes for what are described as "huge" bugs.
