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.
