First, congratulations to UFO: AI team. After more than two years of hard work, they released new stable version (2.3) of their project. There are many changes, related to gameplay and engine capabilities (bump maps, glow maps, specular lighting, etc).


You can download latest version from here.

Meanwhile, SupSuper (author of OpenXcom project) has uploaded new SVN builds (builds made from latest codebase), featuring bulding and dismantling base facitilities.

His project is still in early phase, far from being playable. But if you would like to help with coding (fix some bug, enhance something), you can send him a patch. Head here for more information.
