Zombies Break Doors

Zombies Break Doors

Hiding behind a door used to mean safety.
Not anymore.

Zombies Break Doors is a Forge mod that significantly enhances zombie AI by allowing zombies to break common player-made barriers and now even climb ladders to reach players. Wooden doors, glass walls, and vertical escapes are no longer reliable defenses - zombies will exploit weak base design and pursue players relentlessly.

The mod is fully configurable, highly modpack-friendly, and compatible with both vanilla and modded content.

🔥 Core Features

✅ All zombies can break wooden doors

• Works on any difficulty
• Supports modded doors, including 3-block-high doors such as Dramatic Doors.

✅ Iron doors can be broken (configurable)

✅ Glass blocks & glass panes can be destroyed (configurable)

• Supports modded glass via Forge tags
• Glass barriers are cleared properly for passage (1×2)

✅ Zombies can see through glass

• Players are detected through glass blocks
• Leads to intentional and targeted glass-breaking behavior

✅ Trapdoors can be destroyed (configurable)

• Wooden, iron, and modded trapdoors supported
• Trapdoor-based “fake doors” are no longer safe

✅ Zombies can climb ladders (new in v1.5.0)

• Zombies can climb ladders and other climbable blocks upward to reach players
• Uses vanilla-style movement (no teleporting, no cheating)
• Fully configurable via can_climb_ladders

✅ Vanilla-style block breaking animation

• Visible cracking effect for all door-parts
• Zombies stop, focus, and break barriers over time

🧠 Smarter Zombie Behavior

• Zombies actively hunt players once detected
• Glass no longer blocks line of sight
• Doors, trapdoors, and glass buy time - not safety
• Iron doors delay zombies, but do not stop them permanently

Base design now matters.
