About this project
What does IC2Additions add?
IC2Additions is an add-on for IC2ex that gives you a bunch of fresh stuff to play with. It's all about making your tech progress smoother and the late game more fun.
Please run the game without Advanced Solar Panels and Gravisuite
New Energy Storage: old MFSU cannot handle late game technologies, they are short of space, energy input/output. So we added new Plasmatron, Auraton, Quantum, and Photon
New Crystals: New energy crystals with higher power tiers and capacity. They are used in extended crafting
New Tools: New energy power drills for a better mining experience: Advanced drill, Nano drill, Quantum drill, Vajra, and Advanced Vajra
Weapons/Armor: Strong gear and swords to help you survive basically anything: Advanced nano suit, Advanced quant, and the most powerfull is Molecular Armor.
New Items: various items from forgotten IC2 addons, such as sanarium. We also added new ways of getting energy from reactors: Neptunium, Thorium, Californium
This mode will update as soon as I have a free time.
Goodluck with mining, soldier.
