Definitely Not Overkill is a relatively small pack designed to have as many mods as possible to play around with, while still being able to actually be played on lower hardware. There is a lot to do, such as becoming an experienced thaumaturge, destroying everything in your path as an android, and bending nature to your will with plants. Just make sure not to fall into the black holes!

Do tech things

Do magic things

Dungeons!

Become an android!

Decorate things!

Essentially, do whatever you could possibly dream of doing in Minecraft!
