concrete requiem prototype 01

First prototype for Concrete Requiem FPS game. 

- Its purpose is to test NPC enemy combat behavior (find bugs, weird actions, everything standing out)

- all visuals are placeholder except from the NPC model and material

- the map visuals assets are very simple, but the lighting is more or less what could be used in the actual game. The goal is to evaluate how easy or hard it is to spot NPCs and fight them.
