Have played this on someone else's PC. Very basic tactical turn based combat, worse than the Heroes of Might and Magic games, which are much more playable. Overland movement is particularly bad, slow, and using a 'speed up' button that constantly resets, and still isn't fast enough. Missions aren't interesting and repetitive, and the graphics are bad - particularly for the combat units, they look like little Russian dolls. It's baffling that this is a $30 game, perhaps $7 would be enough. Though it seems to be popular.
Not as great as the original Blood but a clear homage to that era of games. It appears to play more smoothly on 'software' settings for the graphics than 'OpenGL'. The areas were a little dark at times and the gamma needed to be adjusted in the options menu to see what was going on. The bowling bombs don't work particularly well. Kind of missing the sticks of dynamite, also alternate weapon fire is not yet up and running. On the positive side, this demo looks acceptable on high resolution and plays as you would expect. The voice work is engaging and doesn't jar too badly. Don't forget the violence, this is similar to Blood. A few shots can kill you, weapons do a lot of damage. Expect a lot of hiding, running. Very satisfying for those that who that level of difficulty. It's really not bad, better than expected. Looking forwards to the complete game.
