Space Invaders--work in progress

Here's how I'm going to base my Space Invaders army for Hordes of the Things.  (In case you missed it, these figures come from packs of erasers I bought before Labor Day.)

I need to texture and paint the bases; I plan on leaving the figures themselves in their original colors.  While they will all be the same type of element, regardless of which type of invader they are, I'm still debating on how to classify these creatures:

• Hordes, because when you kill the last one, another group appears?
• Shooters, because they lob missiles earthward in the video game?
• Warband, because they implacably advance toward their enemy?
• Flyers, because they descend from space?

I definitely don't want to do Hordes, because then I would have to come up with another dozen stands of figures.  Right now I'm leaning toward Flyers, because I think that's the best fit for invaders from space.

I currently have enough erasers for nine stands of Invaders, adding up to 18 Army Points.  The saucer from the game will provide another 3 AP as an Airboat and serve as the general.  Since there wasn't any kind of saucer eraser for sale, I'm making this myself from a wooden disc, which I hope to show you soon. 

That leaves 3 AP to bring the army up to full strength.  I have an idea of what I'm going to do to fill that gap, but I'm saving it for a surprise.
