lowyhong: Cool so it's a bit like the "<genre> General" games?
The key part about the game is that to place a new 'module' you have to launch it, using a mechanism similar to a basic golf game. You aim in a particular direction, then click to start he 'power meter' then click again when it reaches the power you want. If you've done it correctly the new module lands where you want it. Plus there's wind and other factors.
Of course it never lands exactly where you want it, and that's part of the fun of the game. So you have to combine the strategy of what modules to build and where you want them, and the dexterity element of whether you want to take a risky shot that would put it in a killer spot, or just inch up with more cautious, but less effective placements.
Really a lot of fun, and very novel! There was never anything like it, before or since.
