Simplex started as a branch from Complex. It has combined features from Path To Victory as well as many other mods through a long history of R&D. This mod aims to excavate the full potential of the Homeworld 2 engine and it will simply blow your mind with incredible fun!
The Dark Realm is a passive defense field where the speed of light drops to near zero, rendering everything inside the event horizon topologically insulated from the outside and hence safe once and for all. Unlike the miniature Black Holes created by the Progenitor, the Dark Realm doesn't exert a gravitational pull towards its center.
Just wondering, how would that work without actually making a back whole, though this is a great idea to kind of make some things stay out of combat for a while.
How does it work? Well...They found this by accident in an unsuccessful warp drive test :P
Seems very likely, a lot of inventions were discovered by accident like rubber.
