Tomb Of Thunder - Sleepwalking Through Mud

This is map 2 out of 7 of my current personal project, Tomb of Thunder. I am starting with map 2 and will make map 1 last so it will make for a great start after accumulating map experience from making the rest.
This takes place in a ruined pumping facility taken over by swamps, which has been reworked as a Communication hub, but the rework itself has been sloppy, as it only rehabilitated the main buildings as communication towers.
It went through 5 iterations before I was able to pin down what I was looking for, and the inspiration from Daikatana's E1M1 are apparent.

The rain has been a recent addition, as I always wanted this level to be doused in rain. I want to thank Squid V. for making the initial texture. It was made by making 1-unit curtain brushes all around open areas, and manually placing around rain sound entities. It surely makes for a great atmosphere.

Tomb of thunder is currently a work in progress.
