ZK1L4 v2.2 — Golden Sir, Mutations & Major Combat Upgrade

ZK1L4 v2.2 is here: and it’s one of the biggest updates so far.

This update brings elite enemies, dynamic run modifiers, deeper combat, and major polish to both solo and couch co-op play.

🧟 New Elite: Golden Sir

A rare high-value zombie has entered the battlefield.

Golden Sir:

• Drops large amounts of gold

• Spawns with an escort of zombies

• Switches between fleeing and attacking

• Can suddenly burst into a high-speed sprint

If you see him, hunt him. If you hear him, chase him.

🎯 Run Goals & 🧬 Run Mutations

Every run is now more dynamic.

You’ll encounter:

• Run Goals that reward XP, healing, gold, or skill upgrades

• Run Mutations that change how zombies behave (more enemies, faster hordes, glass-cannon waves, tanky mobs, and more)

No two runs will feel the same.

⚔️ Combat & Enemy Upgrades

• Zombies now use proper collision bodies

• Enemies feel more physical and aggressive

• Improved pathing and stuck recovery

• Elite enemies are more dramatic and threatening

• Special zombies announce their arrival with on-screen messages

The battlefield feels alive — and dangerous.

🎮 Couch Co-op Improvements

• Player 2 now receives full UI feedback

• XP and gold scaling is balanced for co-op

• Controller detection and UI switching improved

• Vibration, messages, and pickups feel better for both players

🎨 Visual & Audio Overhaul

• Cleaner sprites and better readability

• Improved contrast and clarity

• New elite and loot visual effects

• XP and SFX audio tuned to avoid noise spam

🛠️ Fixes & Stability

• Fixed enemies spawning on top of each other

• Fixed physics explosions and flying zombies

• Improved performance and reliability

• Multiple UI and controller fixes
