Originally in Blood you could kick anything, but it became extremely annoying to have stuff flying around constantly. It takes tons of work to get movement right. Getting the movement in Blood to the state it was at for the final game took dozens and dozens of revisions, and getting Blood 2's movement right has required the same amount of work. Most shooters seem to have fairly slow movement that is under-sampled with a pathetic jump. Not Blood 2.
Movement is fast, control is strong, and the jump is good.
We have taken a lot of Blood's original movement code to assure all of that. We'll be releasing the level editor and other tools with Blood 2, and the game source around the same time. Lithtech has been designed as a modular engine, not specific to one game, and this will allow users to easily add creatures, weapons, and other changes to B2. One other nice feature is that many of the art and code source from Shogo and Blood 2 are interchangeable, so mod developers who have both games will have twice the source to work with, as well as two games that play different but will be able to use the same mods. Blood 2 will support any D3D compatible card, but I would recommend going with a Voodoo card, since they have produced some of the best performance, and allow support for all of our features.
