There is a version 2.0 Z: Steel Soldiers demo on GameSpot UK, which should be welcome to those having trouble getting the original version 1.2 UK demo of The Bitmap Brothers' 3D real-time strategy game to run (story). This is now the same version as the US demo released last night (story), but at 55.8 MB significantly smaller to download as it doesn't include DirectX 8.0a (which you probably have already anyway).
