Also I got another suggestion, add features for underwater combat, like for example a spear gun or torpedo launcher.

Absolutely love the mod so far. I suggest making the damage of the guns more damaging. For example, if a gun gets a direct hit from the enemy's gun, it could blow up and actually ignite whatever ammunition that was inside doing additional damage to your base. I also noticed that the nuclear bomb didn't really damage the base in the video. I am assuming it is more for war without exploding the player's build but in my opinion, fighting your friend is also about having fun by doing damage to their stuff not just them personally. With that in mind maybe you could add a "Highly Explosive cartridge" that does actual explosion damage to where it makes contact so players have the option to fight with or without exploding blocks. I also replied to your video that you made a month ago talking about the nuclear bomb. If your interested on my suggestion I would kindly suggest reading my comment.

I apologize, I just re-watched the part with the nuclear bomb and it does explode blocks just doesn't do a lot of damage when comparing it to the rest of the build. I just want to add to my suggestion by once again suggesting that adding a "highly explosive" variant to the nuclear bomb and other weapons/cartridges would be a great addition to the mod. Love the idea and functions of the mod so far! Give my applause to the creator.

The base was made of ultra strong blocks, normally it will completely level structures in a large area, also the damage area is much wider than it is tall. But I like your ideas.

i'd like to see a more in depth video about the firearms and cannons, also do you have an aproximate release date?
