Changelog

⚙️ Engine

• Extended PFF reading from 2 GB to 4 GB.

🚁 Black Hawk Down Event

• Smaller changes for the Black Hawk Down event.

⚡ Crash Recovery

• Removed the 2-minute wait after the game crashes with a sysdump — you can relaunch immediately and get straight back into the action.

🎙️ New Mumble Talkers Overlay

A left-side HUD panel lists everyone currently on voice, with 3D speaker icons floating above their heads in the world.

Talk States

Each talker shows a colored dot and a tag next to their name:

• [LOCAL] — white · proximity voice, only shown within 100 m.
• [RADIO] — green · team radio, shown up to 250 m (fades with distance).
• [WHISPER] — purple · private channel.

Per-Talker Row

Colored dot · name · state tag · distance in meters · compass arrow.

Compass Arrow & Health

The compass arrow points to the talker relative to your facing. Its color reflects their current health:

• ➤Green — 90–100 HP.
• ➤Orange — 45–89 HP.
• ➤Red — 1–44 HP.
• ➤Blue — dead (0 HP).

Speaker Icons

• Float above each talking player: white for local voice, green for radio.
• Alpha fades with distance for radio talkers.

Behavior

• Talkers linger 5 s after going silent (name and row fade out gradually).
• The local player is never listed.
• Shows a "no talkers" placeholder when the channel is quiet.
• Auto-scales to resolution (baseline 1080p).
• Suppressed in FFA game modes (DM / KOTH) — the overlay would leak position and liveness, so it hides itself automatically in non-team modes. Fully active in team modes.

📡 Network Stability

• Fixed TR flashing — high-ping players no longer stall and become unshootable when the connection is unstable.

🔫 Weapons

• Fixed missing 3rd person weapon model for the M16/EOTech.
• Adjusted the EOTech reticle.
• Reworked the EOTech reticle ring to be more transparent.
• Made mortars less accurate when fired without a laser designator.
• Rebalanced mortar damage: reduced overall blast radius, and increased the minimum damage radius so targets within a few meters receive full damage before damage falls off.
• Fixed an issue where the PKM had no weapon sway while using point-aim mode.
• Reworked body armor class availability: removed from Medic; added to Rifleman and Fire Support.

🚁 Vehicle Changes

BTR & Stryker

• Reduced muzzle flash smoke so it obstructs the gunner's view less.
• Retextured the BTR-80 using a camouflage pattern inspired by real-world designs while matching JO's environment colors.
• Reworked the BTR to use the 1PZ-2 periscope sight for the 30mm cannon.

• Added more visible tracers to BTR rounds.

Tanks

• Cannon rounds fired from the BTR, T80, and Abrams now originate from the actual barrel instead of the player camera.
• Fixed the strange bar obstructing the T80 gunner's view.
• Added glass to the Abrams gunner view similar to the T-80 — if shot in the right place, you can break the gunner's sight glass, making it harder for them to see.

Helicopters

• Reduced Little Bird / NB105 health to 5,000 HP.
• Converted helicopter co-pilot seats into emplacements equipped with binoculars for spotting enemy positions.
• Increased NB105 transport capacity to four passengers plus one co-pilot.
• Disabled the NB105 doors from closing during takeoff, making it easier to fire from the helicopter.
• Fixed an Apache and KA-52 multiplayer bug that prevented the 30mm cannon from aiming lower than 10 degrees.
• Helicopter rotors can now kill players when spinning.
• Modified the Apache so the front target optic follows the gunner's head movement, allowing the pilot to see where the gunner is looking.
• Added a gunner direction indicator to the KA-52 cockpit display.
• Improved Puma textures.

Landing Craft

• Increased LCAC and Landing Craft health to 16,000 HP for improved survivability.

🗺️ Objects & Mapping

• Created a jungle version of the DFD3 terrain.
• Improved DJ Mod terrain textures with better color and detail.
• Created new foliage and detail maps for DJ Mod terrains that originally lacked them.
• Fixed 2D number text items not displaying correctly on lower graphics settings.

Memory Fix

This update expands the allocated memory for JO, allowing us to add more content and load very large maps without memory failures. Issues from the previous playtest-like missing UI or sounds on maps such as Cold Water Gap, and occasional sysdump errors-should now be resolved in most cases. Special thanks to @biggy and the RAD mod creators for making this happen!

Weapons

• Added M4 with EOTECH.
• Added M16 with ACOG.
• Added AK47 with PK-AS.

Graphics

MED (Mission Editor)

Thanks to the expanded memory, you can now place more items on maps than before. Previously, MED had a hard cap on how many items it could export to a BMS file. This update includes a patched MED from Biggy that allows exporting maps with item counts beyond the old limits.

Stability note: very large maps or extreme item counts can still cause flickering buildings/items. Biggy is exploring this; a complete fix may not be possible. That said, we can now load very large maps that used to cause system dumps.
