Yup, that was my idea.
And Militia ammo is free.
Standard and above costs you money.
You can't use Militia ammo with Prototype gear, you need ammo that fits your weapon grade.

what would be the point of buying ammo , when you get it resupplied by nano hives and supply depots? Everyone would just drop a nano hive in the mcc the first spawn and defeat the purpose.

It would either be redundant or hell for supply logistics. In EVE, its one thing, but in Dust, its another.

But that is still hell for logistics, either that or redundant, if ammo is one broad thing that is interchangeable, or if it really is unique and nanohives must be supplied with multiple types.

Also, think about it. Ammo is a minuscule cost for frigates in EVE, and those guns are actually pretty massive. Some of the frigate-class turrets are actually dual-barreled 280mm artillery cannons, and the ammunition for them costs very little. Imagine how insignificant the cost of ammunition in Dust would be. It really is unneeded.

Nah, as it is certain weapon types are good against certain type of defense. This creates an inherent balance last thing i want is a Mass Effect type assualt class that can carry multiple types of ammo and and handle all threats with just one loadout.

Yes, I would like to see the option of customizing a gun with ammunition, but I'm still confused about how it would work.

What if you kept your own ammo in stock, and when you went to a supply depot or nanohive, it withdrew it from your own stocks, similarly to dropsuits and vehicles? That would be the simplest option, and probably the best. Of course, there should probably be a default militia ammunition.

You really should have made it more clear about how it worked.
In that case, I support. Ammunition is always fun.

Also, advanced and prototype are sort of like the Tech II of Dust. T2 ammo in EVE is far more significant costing than T1, so I guess that does make a difference. It shouldn't cost too much, though.

It would be interesting to see how people react to ammunition. Perhaps it could be even more varied than in EVE. That would be fun. Gatling guns filled with EMP rounds? No one expected that!

On a side note, do vehicles use ammo? They probably should, then they would park next to supply depots to reload.

Most of the antimatter charge is actually just a containing material. The actual amount of antimatter would likely be much smaller than a speck of dust for a handheld weapon round, and quite a bit of it would be used up just travelling through the air. A true short-range ammo.

Oh, and there should be an option to quickly switch your ammo at supply depots so you didn't have to change your fit. Mostly for convenience.

One step at a time, young padawan. CCP has more important things to deal with first and you and I have a long road ahead in terms of how the game will improve over the years. Haste makes waste.

Ah, yeah....it is a blaster isn't it. I thought it was a rail gun.
