What Lurks Under The Waters of microTech?

I walked into the river of microTech, at night, and started my trek across the river bed on-foot. The lighting effects for the water and how it diffuses light are still impressive. Plus, thanks to some camera angles, I was able to get this cool scene of my Tumbril Land Systems Cyclone-TR shinging it's headlights on the water.

Yes. I am under the water when I took this. I'm glad water isn't lethal anymore, but when are we getting swimming mechanics and other gameplay related to liquid bodies on planetary surfaces and such? Loaded question, I know. Since it's still tentative on the Progress Tracker, and that means "SOON_TM_".
