Defend Your Base From Scary Worm Best Builds and Plot Layouts

A good build in Defend Your Base From Scary Worm is a filled plot with a job for every tile, not a screenshot of one rare. You start with about 450 cash, a concrete bunker, a wooden door, and a night-grass lane. You end, if the all-levels footage is the goal, with printers still printing, mortars still arcing, neon-blue units stacked on the spare tiles, and a door that never slivered. This page is that ladder: starter, mid, endgame, plus the co-op split between repair and DPS.

Rankings for individual units live on the tier list hub, the unit tier list, starter loadouts, and endgame rankings. Use those pages to pick which spear or mortar. Use this page to pick where they sit and when you buy them.

Starter layout — printer plus spears

Claim an empty plot. Do not share a stranger’s tiles on a 35-player server unless you already agreed who repairs. Spend the opening cash on one printer or farm behind the door, then one or two spear throwers covering the approach. Leave a walkway to the hinge so the repair prompt still works (controls).

Starter rules:

• Economy is the back row. If the worm chews a printer, you failed placement, not RNG.
• Spears are the front-ish row, still not on the door tile.
• Empty side tiles are fine at minute one. You cannot fill a plot with 450 cash and should not try.
• Door HP stays near 400. A starter build that ignores the tick is not a build.

This is the same open as getting started and how to farm. The layout version adds one constraint: never trap yourself behind spears so you cannot walk to repair. If you have to jump over your own units to tap the door, you placed wrong.

Mid layout — mortars, second farm, still a walkway

When printers pay real money, stop buying extra spears “because they are cheap.” Put mortars where they cover the lane. Upgrade mortars already placed before you sprinkle new ones into corners that cannot see the worm. Add a second farm if the back row has room. If a farm gets clipped during a chew, replace it immediately so income survives a bad clip — that is a mid-game placement rule, not a flex.

Mid-game still loses on the door. Mortars do not replace repair. Keep cash for the tax, especially around wave 13, which is a money check. A mid build that looks dense but cannot afford a repair is a spear wall with extra steps. Compare mortar value on the unit tier list if you are choosing between two shop rows; do not skip the printer upgrade to win that argument.

Rare units start showing up here. Slot a rare in a tile that already has line of sight. Do not delete a mortar to make fashion space. Do not roll exclusive crates mid-wave; gems wait until the worm is dead (how to play).

Endgame layout — blue unit, filled plot, printers still exist

Endgame is a ~16k blue damage unit (about 120 damage in footage) plus a plot with no wasted grass. The full-clear video ends “neon blue all day” with the base expanded and maxed. That is the picture: every spare tile is DPS or income, the door walkway is still there, printers were never sold to afford the last blue.

Fill order:

1. Keep existing printers and farms. Selling income to buy one blue unit is how Impossible wipes.
2. Mortar line stays. Blue units add, they do not replace splash.
3. Drop blue units on remaining valid tiles that face the lane.
4. Repair through the ~25-second boss countdown. The worm heals; a pretty plot does not.
5. After the bar hits zero (stills show ~748k / 999,999 class HP), bank gems, then exclusive crates.

If you want the ranked version of “what is actually S-tier at this stage,” open endgame rankings. If you want the walkthrough of the heal race, open how to beat the worm. This section only insists that a maxed plot is full, not hollow.

Co-op split: repair versus DPS

Servers hold up to 35 players. That is not 35 mortars on one hinge. A clean co-op build assigns jobs before wave one:

• Repair player: stands on the door, keeps ~400 HP, never opens a crate during the countdown. Reads how to protect the door.
• Economy player: printers and farms, replacements if chewed, printer upgrades on cooldown.
• DPS players: spears early, mortars mid, rares and blue units late. They do not stand on the repair volume.

If you only have two people, merge economy into DPS and keep repair as its own job. If you are solo, you are all three; your layout must leave a path so you can print, place, and tap without a parkour course. How to play is the social contract. This is the tile contract: do not cover the interact prompt with a blue unit, no matter how good the tier list says that unit is.

Layout mistakes that look like “builds”

• Spear wall, no printer, proud screenshot, wave 13 bankruptcy.
• Printers in the chew lane because the back of the bunker “looked empty.”
• Mortars on the door tile, prompt blocked, repair delayed by two seconds, loss.
• One blue unit, rest of the plot empty, calling it endgame.
• Six teammates stacking on one plot, nobody claiming their own bunker.
• Copying Forest / Desert / Freezer / Lava pads from Defend Your Base from 67. Wrong game, wrong tiles.
• Spending cash on a door cosmetic instead of a repair plus a farm.

Starter loadouts on the starter page will name cheap units. They will not save a blocked hinge. If a ranked unit and a walkway conflict, the walkway wins until the worm is dead.

A compact build card

Starter: 1 printer back, 1–2 spears on the lane, walkway to door, repair on tick, ~450 cash spent, not hoarded.

Mid: printer upgraded, second farm if space, mortar line, rares only with leftover, wave 13 still payable, door near 400.

Endgame: printers kept, mortars kept, blue ~16k units filling leftover tiles, plot expanded, gems after the kill, exclusive crate only then.

Co-op: one voice (or chat line) on repair, everyone else on print-and-shoot, no crates in the 25-second window.

Run that card, then argue tiers on the tier list hub. A build is a claimed bunker that can print, shoot, and repair at the same time. If it cannot do all three, it is a pile of units, and the smiling worm is happy to chew the gap.

Fill the grass before you flex a rare. Keep a human-sized path to the wooden door, keep printers behind the concrete, and let the 16k blue unit occupy leftover tiles — not the repair job, and not the farm row that pays for the next difficulty.
