As of a couple days ago, our editor now has the capability to change pallets for individual enemies. This is currently done through the text files that save the levels, but a part of the current work I’m doing will be totally overhauling editor object editing so that you can change whatever detail you want about an enemy through the gui.
There are more than one faction which players will be able to fight in MH, yes. But what the other factions are is a spoiler!
