This modpack is about balanced tech and challenging mobs. This is a hardcore modpack meant for people who want a challenge and build hi-tech bases. It adds powerful and dangerous mobs and reconfigures the tech mods so that they provide the player with a good challenge. Power generation will be a struggle. The main power generation mod in this modpack is Deep Resonance. This modpack also contains RFTools which is reconfigured to be more challenging as well. Efficiency dimlets are not as good as they are normally, dialed transmitters need power, peaceful mode in the environmental controller needs more power and so on.
