Lighting, HD textures and campaign building

The last few weeks I've been concentrating on polishing the presentation and graphics whilst trying to put together some sort of story/setting/theme to the game as a whole. Although the story is not the most important thing in a shooting arcade game but you do need something to tie it altogether still.

I've set up a lighting system to give the scenery some more ambience and am now using high definition mip-mapped versions of the old textures. The lighting looks quite nice, smoothes out the bright flat appearance architecture used to have and will allow me to do some cool effects too but it has come at a performance penalty, I may have to consider going down to 30FPS.
