Early stages of development? All this is is the demo for the Ultimate FPS script pack from the Unity asset store,the terrain has been flattened,there is a cell shaded effect and the gun scripts have been set to infinite clip size.Other than that nothing has been done to this,so unless the person who uploaded this works for the guys who make UFPS then he can't really call it his creation.
Keep at it Mr Martian,this has allot of potential.This is definitely a case of "Simplicity can be the best option" which is not a criticism.It takes something special to make simplicity this much fun. :)
Excellent game,great fun,would make for cool multiplayer too,the big heads and inability to do halo jumps would make the game more accessible to non pros :)
