Mod makes biters spawn and attack in waves.
The intent of this mod is to make the game a little more like 'They Are Billions'.

I made this mod to add a little bit more difficulty to early and mid-game. If you have any suggestions or ideas, please post them on the discussion board and I will try to get to them. This is my first mod for Factorio, so please bear with me, there may be bugs, and I'll try to get them solved as quickly as I can with the time I have available to me. If you're a more seasoned modder, I'm always happy to accept advice, Thank you.
