Note that the sky is slightly blurred as it is scrolling rapidly in the game (looks awesome). The Mechs' cockpits are slightly transparent and also show the moving sky reflected in them! 

It is tricky to get the screen shots as the game crashes after each screen grab due to flicking back and forth to Windows95 but the effect of walking through the transparent flames of an exploding enemy as you hit him with SRM's is superb. I found myself viewing outside the mech often in the game just to watch the graphics :) 

Note: at 800x600 the screen grabber crops the image to 640x480 anyway so i didn't use any of those. In all these pictures the quality of the sharpness is a not as good as the original game screen (!) due to the jpg compression used here. I used the 3DFX grab util available from here for those of you who couldn't find it.
