Battlecruiser - Tactical release
Developers 3000AD recently announced that they had cancelled their Tactical Engagement first person combat add-on for Battlecruiser, partly thanks to the company behind the engine they had licensed for the add-on going bust recently, and partly to allow the company to concentrate on an entirely new game for PC and X-Box using the Serious engine.
Now they have released the latest version of Tactical Engagement, which is vaguely playable but very much "work in progress", along with the full source code for the pack. You can grab the add-on and its manual from the 3000 AD website. And on a brighter note, the company is promising that a public test version of their current project, Battlecruiser Millenium, will be available by September 15th.
