In hindsight, perhaps launching 21 missiles at my enemy was overkill. Oh well. I am become death, and all that. It was still cool. This is a very awesome game!
The second button is to turn on and off automatic replacement once you unlock that option.
This is an excellent game for experimenting for the industrialcraft mod. Now you don't have to set up a whole creative world just for that.
This is actually a really good rts game. It almost reminds me of the old style rts games that were really awesome and no one seems to like anymore. Overall, a really good game.
