Sorry it's been a while since i last posted anything about updating this map, just dug it out this morning and finished it up.
* moved the bottom chamber/room closer to the staircase
* added some small details to the hanging lights
* checked weapon/actor/affinity/spawns
* added waypoints
* added a sniper nest in the wall near the fan room
* fixed some lighting/shadow errors
* textured missing areas
* removed water from teleport room
* removed sparkly circle particles from teleport entrances (they looked odd at a distance)
* removed most of the 'dusty' particles, which weren't working properly due to default maxparticles values
* changed texture in the "hidden" vent passage
* some other things i've forgotten about
https://imgur.com/a/bVW8QShould be good to go, but i'll post it here now so if anyone wants to playtest it and finds any more issues etc.
This map is still focused on these modes;
* deathmatch
* bomber ball hold (spawns randomly across the map)
The reason it doesn't have normal bomber ball mode is because there are no team base locations (if you load bomberball mode, it will automatically change to bomberball-hold)
