Hold the Door Zombie Defense Hold the Door Guides & Walkthroughs
Tower defense tutorials from first unlocks to Subway clears, Rusty Queen, and full lobby coordination.
Hold the Door: Zombie Defense by Zomvex is a Roblox tower defense experience where you and up to 25 players defend a single objective: the door. Zombies march in waves across different maps, elite enemies spike pressure mid-run, and boss fights like Rusty Queen on Mine can end a session if your team is unprepared. This hub collects every in-depth guide on the wiki so you can jump straight to the topic you need.
The game released on March 18, 2026 and follows a familiar loop with a strong co-op twist: earn currency during waves, spend it on unlocking and upgrading towers, reinforce door HP and repair, and expand unit slots so your defense scales with difficulty. Whether you are solo on Lava Pit Medium or filling a public server, the same fundamentals apply—control the chokepoint, spend early money efficiently, and never let the door bleed out during a boss phase.
Start here
New players should read the Getting Started guide first, then Unlock Towers for a role-based shop order. Pair both with Controls if you are learning placement on mobile or switching from another Roblox TD.
Solo versus co-op
Official copy pushes teaming up, but many players farm alone. The Solo Play guide covers Easy/Medium ownership, Hard stall patterns near wave 20+, and when to rejoin lobbies. For full servers, switch to Team Play for role splits and door callouts.
Boss fights and late waves
When the announcer warns of a boss, open Beat Bosses and Mine and Rusty Queen. Boss phases punish greedy spending—if you unlocked flashy units but forgot door repair, one ability rotation can wipe your run.
Maps and pathing
Start with the overview Maps guide, then drill into Lava Pit, Subway for Club King Easy and King Viking Medium corridors, and Mine before boss queues. Use the Difficulty Picker when you are unsure which queue fits your unlocks.
Economy, tips, and habits
Deepen spend rules with Economy and Door and keep Tips and Tricks bookmarked for skip votes, callouts, and choke habits.
