So I was thinking about a concept of an isometric survival game focusing on the lack of food and equipment. One point I was stuck at is that if the player has very limited resources then they should be able to get the best out of them, and there comes the concept of precision into play. If, let's say, you have 3 bullets and 2 monsters are attacking you, then you should be able to aim and try to get a head-shot on them. The issue is that I have no idea how I would simulate/fake/create an illusion of the third dimension in such a setting. I would like to hear your suggestions or alternatives to improve on my point of the game.
