Q: Does this mod work with multiplayer?
A: I don't see why not, but I haven't tested it. Be sure to raise an issue at the GitHub source repo if there are multiplayer issues!
Q: Are there any caveats/flaws?
A: In 0.3.1, technically, the ammo is no longer infinite, due to Factor 1.1.57 changing the magazine size limit from infinity to just a very large number (somewhere around 34e37), but in practice, the ammo sizes are pretty much infinite (you deserve an award if you can manage to fire ~340 undecillion bullets from a single weapon in Factorio), so the mod name shall stay the same.
Q: Will this mod affect my in-game performance/UPS/FPS?
A: There is zero runtime scripting in this mod, so there should theoretically be no affect on performance.
Q: What are the recipes of all the infinite ammo items?
A: The recipes for all added items are 1 Stone + 1 of the original, non-infinite version.
Q: Are there any incompatibilities with other mods?
A: Almost certainly not. However, if you do somehow find an incompatibility, please open an issue at the GitHub source repo. However, any mods that make modifications to ammo in the Data Final Fixes stage may cause issues.
Q: Are there any dependancies on other mods, and why?
A: In versions 0.2.0 and above, there is a dependancy on Rusty's Locale Utilities, which is a tool used in this mod to help automatically generate locale names and descriptions. Big thanks to 'theRustyKnife' for making that amazing library.
Q: My question wasn't answered here!
A: Open a discussion at the GitHub repo's discussion page then! I might even add it here if it's a solid question.
