I’m happy!  Ahead of the game here…  17 hours left in order to get a nap then work on some levels.  Woo!

Sorry, no playable snapshot at the moment.  But here are some screenshots:

An idea of what is going on:  You are an infiltrator into a military base which has been occupied by two armies.  Resources are low, so you have no weapons, but your mission is kill everybody in the base while making your way to the next area.  Enemies can be made to respond by your approach.  From there, you can either use in-world hazards or other enemies to dispatch them.
