What Does This Mod Add?
New reload mechanics:
-
[]A Bullet in the Chamber that gives you one extra round on partial reload.
[
]Optional Tactical Reload Mode so that only TR enabled weapons will use this feature. This means that you will never need to patch any weapons out.[]Ammo Drop when reloading. You can either drop your ammo on the ground or have it disappear forever. This also takes into account the extra bullet in the chamber and you will drop 1 less than what you currently have in the weapon.
Immersive ammo checking:
-
[]An Approximate Ammo Check Hotkey that displays a message with roughly how much ammo you have remaining in the magazine e.g. about half.
[]An Exact Ammo Check Hotkey that displays the exact current, max & reserve amounts as well as the name of the ammo currently in use.
[]Simple animations (lowering and raising the weapon) and foley sounds while checking ammo. Compatible with all weapons, without patches.
[]Perfect for minimum HUD, maximum immersion players.
[]If anyone wants, they can message me to contribute by making voice lines via xVASynth for this mod.
[]Be sure to let us know if you want to make or already have custom ammo check anims for your weapons and want them to work with this mod!
New hotkeys:
-
[]A hotkey to seamlessly change your fire-mode. Implemented differently from other mods that do this such as ECO. This does not require the weapon to have native semi-auto firing sounds built in, making it compatible with all automatic weapons.
[]A lower/holster weapon hotkey. Short press to lower, long press to holster. Includes a "speed walking" fix to slow animations while weapon is lowered.
[]A reload/check ammo hotkey. Short press to reload, long press to check your ammo. This hotkey is currently incompatible with Tactical Reload Manual version; use vanilla reload key instead.
[]Separate throw grenade and melee hotkeys.
And more...
[]Ability to make throwing grenades require your weapon to be holstered. Now that's immersive.
[*]The ability to turn every single feature on/off through the Mod Configuration Menu. This makes it compatible with practically everything depending on what features you plan to use.
