Hi, thanks for holding off. There are bloody hand prints on the walls pointing in the direction you need to go. The gun emits a flash of light when fired. The baking of the lightmaps was a bit of a faff to get working so I just had to publish where I had got to. Perceptually the Mobile version looks darker than the PC when I was testing with my Q2 with a link cable, but they are playable as it is not totally blacked out. Just don't drop your gun as I haven't sorted out distance grabbing!
