Have some balance suggestions
Hive Launcher: since its a medium Swarmer, it should have 100 dmg/shot to match up with vanilla's buffed Swarmers. It could probably do with much more ammo too, since 2 small Swarmers have a higher combined fire rate and the same ammo for much less OP.
David missiles: I like the concept, but they seem quite underpowered, especially compared to the budget missile options in other mods. Even if they are just meant to be a substitute for people who can't get Harpoons, their tiny range and bad tracking means they are unlikely to do anything meaningful. An ammo buff could be good to make them a somewhat viable choice. Perhaps 5-6 for the small and 18-24 for the medium? Most rockets have longer range, far more potential damage, and higher hit probability than the Davids. Also I think the medium should get its OP reduced to 9, since its meant to be a cheap alternative to the Harpoon Pod which is 10. Small thing but that's what I think.
Mag Accelerator: seems to be a very strong choice, even with it being somewhat inaccurate. Since its essentially a HighEx Railgun with EMP, it probably needs an OP increase to 7 or 8, and a reduction to the EMP damage maybe to ~200.
Mosychlos BAG: a very strong choice currently. Even with the low hit strength and accuracy, the range and flux efficiency is incredible. It could do with a hit strength decrease (to about 35) or a big flux cost increase.
Aton Burst Laser: this weapon seems quite useless at the moment. Bad range for a large beam, terrible flux efficiency, low damage for a large. Needs quite the buff.
In addition, some very minor capitalization issues: Heavy mining beam, Ice bomb, and MB-3 PDS array should probably be completely capitalized like Heavy Mining Beam, Ice Bomb, and MB-3 PDS Array in order to maintain consistency.
