Cheaper Double Ammo

Halves yellow/piercing ammo cost (with extra output), speeds up all assembling machines, gives AM1 a module slot, extends gun range, and scales module tiers 2 and 3 from your level-1 module stats.

Works with or without Bob’s, AAI Industry, Space Age, and Adjustable Modules and Beacon.

Ammo
- Firearm magazine: 2 iron plates → 2 magazines (vanilla 4 → 1)
- Piercing rounds magazine: 1 firearm magazine + 1 steel plate + 1 copper plate → 4 piercing (vanilla 2 magazines + 1 steel + 2 copper → 2)
- Steel stays at 1; item recipes can’t use 0.5. Other costs are halved and output is doubled.

Assembling machines
- Crafting speed ×1.5 on every assembling machine: vanilla AM1–3, Bob AM4–6, electronics assemblers, chemical plants, oil refineries, centrifuges, Space Age plants, AAI machines, and any other assembling-machine prototype
- Example: electronics assembling machine 1 goes 1 → 1.5
- Assembling machine 1 gets at least 1 module slot (speed / efficiency / productivity / quality, same allowed effects as AM2)

Modules
- If you change level 1 module stats (including with Adjustable Modules and Beacon), tiers 2 and 3 follow automatically after a restart
- Tier 2 = 1.5× tier 1
- Tier 3 = 1.5× tier 2
- Applies to speed, productivity, efficiency, and quality modules (and extra Bob tiers if present)

Range ×1.5
- All guns (pistol, SMG, shotguns, rocket launcher, tank/spidertron guns, etc.)
- All ammo turrets (gun turrets)
- Does not change laser, flamethrower, or Tesla turrets

Everyone in multiplayer must use the same version.
