📋 About This Mod
Out of the box, ACE adds breakdown recipes to every ammo variant of every caliber in the game, from . 38 Special to Pulse and Bean Bag ammo, and crafting recipes for some others like AP and HP, along with downgrading recipes for higher-level energy ammo. With the TTW patch, ACE blends with its . 22LR recipes, and any optional features will affect TTW's own recipes as well as the Ammo Press system, and some ACE's recipes will adjust to maintain a consistent experience.
Crafting & Breakdown Recipes: Literally every single vanilla cartridge has a breakdown recipe (Surplus breakdown is disabled by default, however), and every single cartridge has a crafting recipe other than . 38/. 44 Special, . 223, and Plinking/Surplus. Max Charge and Over Charge energy ammo can be downgraded to regular cells/cores/packs. To make . 22LR and Bean Bag recipes (and rubber ammo, if enabled), I've added some new items: Case, . 22LR; Case Box, . 22LR; and Rubber. You can get all these from vendors and by breaking down ammo. The TTW patch covers . 32 ammo as well.
Balance & Consistency Changes: Several crafting recipes have had their required skill level tweaked, and most breakdown recipes now require a 25 skill level, with special ammo like Pulse or Incendiary requiring a higher skill level. For consistency, all ammo types have been changed to follow a unique naming convention, and all perk tags are consistent through all ammo types. You can optionally remove GRA tags, perk tags, and choose an expanded name instead of an abbreviated one using MCM or the . INI file.
This is all ACE does without further tweaking, you can leave it as is if you're after some QoL features for a vanilla-like experience. However, ACE as an Overhaul can do much more by editing the . INI file or using MCM. The following features are disabled by default.
List of new ammo types added:
9mm: AP, JFP, Surplus, Rubber.
10mm: AP, JFP, JSP.
12. 7mm: JFP, JSP.
357 Mag.: JHP, SWC, Surplus.
44 Mag.: JHP, JFP.
5. 56mm: JFP, JHP, JSP, Rubber.
5mm: JFP, JHP.
. 308: JFP, JHP.
. 45-70 Gov't: JFP, JHP.
