Eurogamer have recently posted a preview of Echelon from publisher Akaei. Included with the preivew are two new screenshots from the build. Here's a taster:
"Overall the graphics are eye-catching even at this early stage. Vast open terrain stretches off into the distance, with the fractal landscape giving the game a truly alien feel. Explosions are another high point, with destroyed vehicles splitting into several smaller pieces that streak off through the misty sky trailing smoke and debris like something out of Deep Impact."
