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!
Only issue I have is that most Capital ships DON'T have afterburners. They are slow, sluugish manuverers by nature. Not sure about that feature being included.
Strike Craft, Corvettes and Frigates I can understand, but not the heaviers ones.
Other than that, everything else looks good.
That's why these are not called "Afterburners" on the capital ships, I named them "2nd Stage Thrusters". Open your research menu to have a look at their descriptions :)
