We are currently tidying up and finishing version 0.1 for release this week.
Ah. That's why I couldn't find it when I looked for it on Steam.
With regard to the increased weapon load causing issues with insufficient power, may I suggest that any increase in weapon slots be balanced by an equivalent increase in support slots? Do these bigger modules by any chance have somewhat higher HP, so as to straddle the difference between the original class and the next one up the chain?
Further, if there is any way to unlock such new modules by making them tech to research, that would be absolutely fabulous. Of course it will heavily weigh down one branch of the tech tree, so maybe there would be a way to fill up the other branches with something appropriate? Perhaps cooperate with some other additional tech mod, where you fill up engineering with better ship modules and they fill up the other branches?
