I'm pleased to announce development for a new version of the game. See the gcblue.com wiki for screenshots and more info: http://www.gcblue.com/wiki/index.php/GCB2

Text from the wiki:

Global Conflict Blue 2 (GCB2) is the next version of GCB, the open source real-time naval and air war game. GCB2 development started in January 2007 as a port of GCB using the Truevison3D graphics engine. Continuing work has advanced game capabilities, leveraging the TV3D engine to provide high quality graphics while allowing game development to focus on game play.

* Truevision3D DirectX graphics - Graphics handled by Truevision3D engine using DirectX for better compatibility with Windows systems and faster frame rates
Open database and art - Database, scenario files, AI scripts, and 3D models will remain in an open format. Players can study and modify game files with commonly available editing tools. Game engine code is not available for distribution. GCB2 engine code may be available as GPL open source in the future. The Truevision3D library is commercial software.
Global bathymetry data - Ocean depth data has been added to maps
Improved GUI - Improved start screen and multiplayer lobby GUI screens
Game loading and saving - Game can be saved to a file and loaded later to resume play
Customizable air loadouts - Air loadouts can be customized in the database and are automatically linked to game controls
Naval formations - Surface ships can grouped into formations and dynamically repositioned during game
Bug fixes - Many small bug fixes
More - Much more to come!

Beta release

A closed beta release of the game will follow soon. Please email beta2@gcblue.com if you are interested in participating in early testing.

Looks really good. Hope I will actually be able to run this version. =/

Beta release 1.0.8

This version is mainly a scenario editor upgrade. See the tutorial pdf for an example of how to use the new scenario edit mode features. Some development tools were updated so OpenAL and VC Redistributable may have to be reinstalled (normally these are installed by default).

Version 1.0.9
http://www.gcblue.com/files/install_gcb2_109.exe

Bug fixes
- Fixed crash to desktop that happened when viewing near North Pole sometimes
- Fixed map data error where thin strip of land near E180 deg longitude was all set to 0 m height

Simulation updates
- Radar model supports "look-down" performance degradation for targets within clutter horizon. One case for target over land, another for target over water.
- Sensor models support elevation coverage and elevation accuracy for height finding

Interface
- Scenario editor now correctly saves scenarios with more than 2 sides
- Added Tutorial/ScenarioTemplate2 scenario as template with 3 sides (third side neutral to other two)
- Clicking on platform in Platform Summary panel (upper left) now changes tactical map region automatically to make it easier to follow action over large areas

Database changes
- Added MinElevation_deg, MaxElevation_deg, ElevationError_deg to all sensor tables (radar, sonar, optical, esm, ecm)
- Added ElevationBeamwidth_deg, LookdownLand_dB, LookdownWater_dB to radar table

Here's a version to try out for testing the new database format, install on top of old one (backup first):

This is not the next release.

Beta Release 1.1.0

Highlights:
- Support for windowed mode
- Damage model has reduced random damage variation
- Added area goal type so win/loss conditions can be based on reaching a location
- Waypoint editing has been improved. You can create new waypoints by clicking on a leg in the middle part and dragging out a new waypoint. Or click and hold and hit the delete key to remove a waypoint. Right clicking a waypoint brings up a menu to allow you to set speed, altitude, and add tasks that are triggered when reaching the waypoint.
- New air mission editor
- A few new database platforms and associated equipment, much more on the way
- Lots of other small fixes and improvements
