TL;DR
Atomic Bomb being dependent on Explosive Rocketry and Rocket Damage 5.What ?
Make Atomic Bomb research dependent on Explosive Rocketry and Rocket Damage 5.I'm going to go against guides and I'm going to suggest 1 more change in the same topic:
Make Uranium Ammo depend on Bullet Damage 5, for the same reasons listed as the last two lines in this post.
Why ?
The Atomic Bomb is pretty much THE endgame science. It costs 5 times what Rocket Silo costs!!That's why I find it weird that the prerequisites are much lower for Atomic Bomb.
I also feel that it would be very logical to start researching Atomic Bomb, because you already have explosive rockets, have researched to increase their damage and still, you aren't satisfied, so you research Atomic Bomb.
It just makes more sense on a lore level.
