NEW REAL-LIFE BULLET SYSTEM

Bullets are now fully simulated like real projectiles.

  • Real gravity drop

  • Wind deviation

  • Real-time ballistic HUD calculation

  • True projectile travel (no hitscan)

  • Real penetration and impact physics

Every shot now behaves like a real-world ballistic simulation.

COMPLETELY REWRITTEN AI SYSTEM (FROM SCRATCH)

The AI is now brutal, tactical and reactive.

  • Fully optimized new AI core

  • Enemies hear gunshots, footsteps and impacts

  • They investigate last known position

  • Search areas dynamically

  • React to sound sources

  • Hunt you down instead of standing still

No more dumb bots. They stalk, flank and hunt.

NEW 100% PHYSICS-BASED HELICOPTER

A fully physical helicopter with real aerodynamics.

  • Real lift, drag and torque

  • Real inertia and weight

  • Real crash physics

  • Real damage behavior

Flying now feels dangerous, heavy and real.

INSANELY REALISTIC PHYSICS DOORS

Doors are now full physics objects.

  • Procedural hand interaction

  • Lock system

  • Physical hinges

  • Breakable

  • Push, kick, breach, shoot

No animations. Only physics.

IMPROVED VEHICLE PHYSICS

Vehicles now react realistically to combat.

  • Wheels can be destroyed

  • Tires lose air and start hissing

  • Vehicle handling changes dynamically

  • Real hit reactions

You can cripple vehicles instead of just exploding them.

EXTREME OPTIMIZATION (BRUTAL CPU FRIENDLY)

Massive performance rewrite.

  • Gore system optimized

  • Physics optimized

  • AI optimized

  • Spawner optimized for CQB

  • CPU usage dramatically reduced

More enemies, more physics, more destruction β€” at higher FPS.

NEW WEAPON β€” KRISSIAN

A new brutal weapon added to the sandbox.

NEW ITEM β€” FIRE EXTINGUISHER

  • Extinguish fires

  • Physics-based interaction

  • Can be used as a weapon

NEW ITEM β€” OIL BARREL

  • Explosive

  • Physical

  • Chain reactions

  • Fire propagation

NEW PHYSICS IMPACT SYSTEM

  • New impact sounds

  • New dirty hit FX

  • Real physical reactions

Hits now feel heavier, dirtier and more violent.

CLIMBING FIXED (FREE HANGING)

Free-hanging climbing is back to full realism.

  • Procedural body positioning

  • Real hand placement

  • Physical weight transfer

  • No animation snapping

Feels like the original realistic system β€” but better.

INSANE AMOUNT OF BUG FIXES

Hundreds of fixes across physics, AI, animations, UI and performance.
