Hi there i am looking for a newer Version of the Invasion Mod ([removed link]). All downloads i have found were very outdated (1.7.10 and lower), but this article ([removed link]) says it is not. What i would like to find is the mod for 1.9 at least, i am not able to find it on my own. If there is no new version, you may recommend a similar mod? All i need are a lot of mobs that are capable of destroying/invading a certain base. My current alternative are withers, but they are too ignorant and often just fly away and don't care what is going on. Any ideas?
