The premise I'll be toying with is effectively the last defense of a once prosperous nation. In the bunker with only a radio, the player will be stepping into the shoes of the leader and commands the defending army to survive and weaken the enemy squads as they push their way in. Theme factors in with the player starting with a fairly well sized army, but loses squads and units as the game goes on. Surviving as long as possible in this decline is the player's main goal.

Due to limited time and skills, I'll probably be running it as a turn based-ish system where you issue commands to your groups and each turn time-skips 4 hours in world to show the results, as the player can't see the field, only a paper map and tokens. This is mostly to work around limitations of art assets and implementation in the weekend time limit.

That's mostly a high view concept of the idea. Tonight I've roughly planned out the potential core of the game and will probably begin rapid prototyping tomorrow morning. The scope isn't very large, so it should be just enough to cry in the fetal position and still get something functional. Tools are Unity3D for engine, Krita+GIMP for art, and realistically, probably not much in the audio department.

Did I mention everyone is magical critters? That may factor in how I handle some stuff.
