Made sure the Blue Horde only starts when you have a few people in your community.

Added a giant Blue Horde that will attack your base. Will catch new settlements off guard.

Added a 'Siege Horde' that consists of armoured Red/White strain zombies when you have a small community going. Should provide some challenge early on the game and catch underprepared players off guard, especially those that grow too quickly!

Added a 'Super Horde' that is active once your community reaches 10+ members. Hopefully adds a bit of later game difficulty.

Added one bigger Green Strain Horde for testing purposes. Once it works, will add different strains.
