Trigger Alien invasion

[JaJe]

Hello!
I've made this video just before the 0.17 update while testing something with creative mode and exploring with Alien Biomes mod. I got an Ideea which actually resulted in an interesting alien invasion and I kinda liked it. Unfortunatelly I didn't know the cheat (if exist) to force spawn behemoths only for even more fun. I hope you like it aswell.

This is how aliens attack should be in my opinion, multiple aliens from multiple directions at same time.

You can spawn an arbitrary number of enemies with the map editor in the console (disables achievements). It supports direct placement. https://wiki.factorio.com/Console#Scrip ... t_commands

Type `/editor` in the console window (open with ~ key)
