Hi,

I've been exploring this game the last couple of days, and I'm trying to get a handle on the tech tree and all the various advancements. I can't seem to find anywhere in the manual or in the game that shows exactly what the difference is in the different levels for various components. For example, exactly what is the difference in a lvl 1/2/3/4/5 Depleted Uranium Cannon? Is there a chart somewhere with all this information on it?
