The demo does show a lot of promise and really is the best of both old and new style FPS games. By restricting development to an old engine while using ideas that have evolved the FPS genre the result is a game that feels natural to play. You run and gun fast but you also have modern conveniences that don't get in the way of the game. Hunting down hidden paths/switches took a little readjusting to but once you get the logic of that down the game is fast and fun!
