Hi, really enjoyed your mod!

There are some little things that I think it would be nice to change

I think that at the moment the technology is very cheap, I'm sure that such missiles should be after artillery at least, I think that a customization here would be appropriate, which research flasks would be needed to acquire this technology

Another moment with FPS, launched a missile with 30 nukes, the game got up thinking in 5 FPS.
I think it could be solved if it all counted as one big explosion, not 30 regular ones, it is logical in general that with such a game stands up.

I would also like for such a rocket sound, I think it is a very important part that can show that the enemies are flying far from just some fart, and a huge rocket. Need a strong noise sound at launch, the jet engine is very loud, during the flight of the rocket, I think it would be nice to have some whistling, maybe more sounds, such as when an airplane flies faster than the speed of sound.

Thanks for your mod, I really hope you continue to work on it, having ballistic missiles in the factory is very cool!

Thanks for your post. I'm glad you like the mod.

I'll check the technology costs. Since I added it a long time has passed and it is definitely not optimized for space-age.

Merging explosions is tricky since a majority of modded ammo types are supported. Using 30 nukes always has bad impact on performance, it does not matter if you use them in the missile silo or not and since 30 nukes are never needed I think the merging-explosion-priority is quite low.

To be honest, I have no idea of in-flight-sounds are possible. I don't want to annoy a whole multiplayer server with sounds that can be heard when the missile passes over you. As far as I know some players start the missiles preferably by logic and in high number.
Is the missile-start sound not to your liking? I tried to find a sound that fits the missile since it is smaller than the vanilla-rocket.

I'll continue working on it for sure. At the moment I have a lot to do in terms of real life work. Will be better after Christmas :)
