Thanks to author Skorpion for creating and revising the firearm sound effects for this mod. ISeeThem is not a required mod, it can be used when playing in 3D mode.
# MOD Notes for Gameplay 1. **Place this MOD at the bottom of load order, mandatory!** Prevents most mod conflicts. Multiplayer compatible. 2. Hold a firearm and press <T> to open inspection UI. Left-click attachment slot to equip parts; double left-click to remove. Attachments must be inside main inventory to install. 3. Firearms, attachments and magazines can be dismantled into components. Use components to craft magazines or repair kits. 4. Guns and attachments spawn inside unexplored military crates, valid for existing save files. 5. Incompatible with all other mods that add suppressors; no required dependency mods. 6. If bugs persist after update, unsubscribe then resubscribe the mod. 7. Advanced Warfare Framework is for mod developers only; regular players do not need it. 8. Current content: 124 firearms & 145 gun attachments, all custom-commissioned by sponsors.
9. Do not use Gunwork Framework together, it is conflicting with MFS and will cause the magazine to be unusable
**Update Notes (Build B42.20)** • New ammo reloading system, all recipes must be collected and unlocked in-game. • Added new firearms and matching weapon attachments. • Complete UI overhaul with 5 new functional buttons: fine-tune attachment position, repair weapons, pack ammunition, unpack ammo boxes, and open trade interface. • Support direct attachment installation from inventory or nearby surroundings. • Added new weapons: underbarrel flamethrower and direct-fire grenade sniper rifle. • Expanded attachment attributes, adding critical hit chance and critical damage bonuses. • Added new items: lightweight backpack and automatic reloading device. • New configurable options in ESC Mod Settings: toggle attachment display for a cleaner UI and adjust gunshot sound volume. • Fixed audio issues: missing gunshot sounds and duplicate gunshot sound effects. • Fully compatible with game version B42.20.
