That's the way the old worms where made. Although you could grab the pixels that are blown away and then insert them into a particle system if you where feeling frisky :)
I made a game like worms once where I had a scrolling background and then an image with 0 representing the color key (so the background showed through) and then when some of the image was blown away I simply filled it with 0. When moving my soldiers I simply tested the image for color 0 to see if they could move there. (Their bounding box that was).
Hope it helps.
Where can I find the game represented by the last screenshot? It looks cool :)
