I've always had an affinity with water-based levels, so I love the idea of exploring this place. Very well done. Also, I like the nods towards Trilogy levels, especially the thoth levels, and other architecture from My Private Thermopylae. The only quibble is a lack of varied texturing, but that's easily fixed.
An underwater map built in and around a scaled-up generator.
You'll need to do some swimming here; set your run key to something easy to reach if you haven't already.
Psycho Physics file:
*Movement is quicker underwater.
*All weapons fire underwater.
*Fusion Pistol fires safely underwater.
---NEW---
*All shots, including monsters' shots, will now fire underwater.
*The S'pht will not float to the top of the map. Instead, their "jump" height is left at it's highest.
The latter additions were made to make Psychomanteus more compatible with the Survival.Lua script. Enjoy.
