Unit Graphics: Doppleganger
Here's some attack animations I did for Battalion Arena over at Kongregate.com The game's developed by Urbansquall and is one of the more popular games on the site.
Apologies for the obvious use of layer transparency. I hear it's frowned upon this side of the internet, but for the sake of the game's quality I had to include it. I hope I can be forgiven for breaking the pixel code!
It should be noted that the unit graphics are not made by me but made by resident artist here Doppleganger. He made the vehicles whereas I animated the actual gunfiring, so it's a joint effort between us. http://www.pixeljoint.com/p/3968.htm
There's roughly 60+ colours, I'd imagine.
