What is Beyond the Red Line
Beyond the Red Line is a stand-alone total conversion for the award-winning Freespace 2 released by Volition and Interplay for the PC. It is based on the popular new tv-show Battlestar Galactica. No, not the one from the 70s.

Will I need Freespace 2 to play it?
No, Beyond the Red Line is a stand-alone conversion and will not require Freespace 2. All you need for playing will be included in the download.

Is it free?
Absolutely. The game is made by fans for the fans, no profit is being made from any part of the project. Although we could use some pizzas and coke to keep our mortal bodies running.

That about covers it... a BSG total conversion of FS2 that has just released a demo version. it plays really well and looks amazing. a must for any BSG fan.

p.s. the linux version can currently be downloaded only via a torrent

p.p.s. this demo contains spoilers for the second season of BSG, so if you haven't seen that season yet you should pass on this game for now.

BGBlitz is a program intended to be the ultimate in Backgammon software. It hosts strong Backgammon playing Bots, training aids, tools to analyze matches and any further features which are requested.

The current release version 1.0 has the following features:

• A neural net, called TachiAI, which has learned to play worldclass Backgammon. For beginners there are also weaker levels available.
• You can set your opponent to be human (useful for entering matches from books, etc.), network (to play against someone over TCP/IP) or TachiAI (the computer opponent). In the release 1.0 there's just one computer opponent, TachiAI. BGBlitz is designed to be able to host several bots and in the future there will be additional computer opponents.
• You can play Backgammon or Nackgammon (a variant leading to more complex games)
• Select your language between German and English. Other languages will follow, if there's demand.
• You can train yourself with difficult positions from the quiz databases. You can download databases from the BGBlitz website or create your own.
• You can analyze (best moves, evaluation, cube action) any position at any time, save positions and continue playing from a saved position.
• BGBlitz has a calculator included which computes the important parameters for cube handling in matchplay, a useful aid in improving your cube decisions. You can choose from three popular match equity tables as the basis for the calculations.
• You can replay, analyze and annotate your matches with BGBlitz or matches from many other sources such as FIBS, GamesGrid, etc...
• You can collect matches in databases and select specific games (e.g. all matches from your next opponent in a tournament). Additionally you can calculate statistics, such as which openings are played and how successful they are.
• There are a lot of formats for matches. With BGBlitz you can read many of them and convert to some other match-formats.
• You can read logfiles from FIBS/W and MacFIBS with BGBlitz, so you can analyze your online games later.
• With the included endgame-database you have very precise winning probabilities available and can improve your endgame play.
• You can have a customized appearance and a wide range of settings in BGBlitz to your own personal taste.
• You can copy a character representation of the current position to the clipboard. This is useful for sending positions in an email or newsgroup postings.
• To prove that TachiAI doesn't cheat, you have full control of the initial value of the random number generator.
• For the evaluation of long races, you can calculate the Kleinman count.

  BGBlitz 1.0.5 has played on the 7th Computer Olympiad and won the Backgammon tournament. The matches are here.
