  • Their equipments become stronger and stronger as the Wave proceeds.
  • You can customize the system,the reward and monsters' equipments flexibly.
  • Some more ideas to reduce lag.


  • Less kinds of monsters.
  • Route searching algorithm is heavier than InvasionMOD (InvasionMOD uses the one same as vanilla. This mod uses original one.)
  • Engineers break and put blocks much more so someone who doesn't want to be broken their structure might not like this mod.

How to begin?

To begin an invasion,you have to craft "Base Block"(one iron block , two iron swords) and "War Declaration Paper"(one paper, one iron sword).

Place Base Block on a place where will be your base and use War Declaration Paper on it.

Then,after searching spawn point, monsters will come to invade.

  • This mod is laggy when starts
  • Scaffold block will automatically disappear after the war ends.
