Majesco Entertainment has announced that Serious Sam: The First Encounter HD will be coming to Xbox Live this fall, and to the PC sometime later. It's a remake of the original game using the CroTech engine, and it will support up to four player co-op. Joystiq has some screenshots, including a comparison between the old graphics and the new look. "The textures are sharper and cleaner than before. The original's perfectly flat lawns are now replaced with individual blades of grass — and look at that foliage, rendered with some classy Crysis-styled soft focus. Notice the dynamic shadows over our pumpkin-wearing, chainsaw-wielding friend? Now, imagine this level of detail on hundreds of on-screen enemies."
