Instead of changing reds to alien kills; how about BOTH option must have red tech and kill biters to advance tech. research only activates when you ALSO HAVE the science. nice combo with https://mods.factorio.com/mod/LootMilitaryScience

Have Zero Tech Researched.

Addition of Enemy Kills WITH BOTH Required Recipes in order for Tech to grow. No Kills no research progression.

for 1.0

Sorry for not responding for 4 Months, I will update the Mod to 1.0.0 and add a option to not start with free research, unfortunatly I dont know how to have both Science and Kill research
