About this project
What does Mekanism x Nuclear Science: Dark Matter Addon add?
This mod adds 12 new things to the game:
Dark Matter (Gas) - gaseous state of dark matter
Dark Matter Pellet - solid state of dark matter
Dark Matter Core - needed for crafting
Quantum Alloy - needed for crafting
Quantum Control Circuit - needed for crafting
Dark Matter Injector - needed for crafting injectionpad
Dischargepad - much like the "chargepad" from Mekanism, instead of charging the suit/equipement, it draws power out of the suit.
Dark Matter Injectionpad - when either the IR unit or module is installed, it fills their internal storage tank.
Void-Singularity QIO Drive - A QIO drive 16x larger than the Supermassive QIO Drive.
Implosion Reactor Unit - Used in the MekaSuit from Mekanism, this unit is a microreactor that uses Dark Matter as an energy source to generate unfathomable amounts of power (FE).
Implosion Reactor Module - Used in the Chaotic Chestpiece from Draconic Evolution, this unit is a microreactor that uses Dark Matter as an energy source to generate unfathomable amounts of power (FE).
Subatomic Recompiler - Used to create literally any time (aside from command blocks) in the game at the cost of power and Dark Matter. This works for all loaded mod items.
ENJOY!
