Quote from aaron_da_killaGreyfrog Design, that looks cool. The cave architecture is quite nice. Make sure you have some sweet non playable spaces that the player can see but not get to to create curiosity and make the player feel like he is in a small part of a larger world (rather than feeling boxed inside a Counter-Strike source map).
That is something I have forgotten to do with this one... funny. It makes all the difference to have areas not accessible to the player. it helps to border the maps and as you've said create curiosity. good comment thank you.
