The original Halo game sparked a revolution in first-person shooters and is perhaps the main reason the XBox has shifted so many copies. This peculiar version is not a new installment of the game but more a 2D conversion of the previous three. Thankfully it includes the same weapons, same enemies, and an enormous amount of levels to negotiate.
Hell on Earth Trilogy certainly presents a large enough challenge to keep you coming back for more for some time. Compared to the originals, however, the 2D action is far less emmersive and you don't get the same fear factor as turning a dark corner to be welcomed by a room full of flesh-eating aliens in this side-scrolling affair. Nevertheless this game is free and enjoyable in its own right.
