Mycopunk Upgrade Patterns: Shapes, Adjacency and Why Position Beats Numbers

An upgrade pattern in Mycopunk is a shape, not a stat line. The same Rare cell can be placed as a straight bar, an L, a triangle or a hook — and where that shape lands on the hexagon board changes the build far more than the number printed on it.

If you have been picking upgrades by rarity alone, your ceiling is around threat 4. Reading shapes is the difference between a build that clears Onslaught and a build that has four great cells and no plan.

Read the shape before the stat

Every pattern resolves into three things:

• Footprint — how many cells it eats. Standard 1, Rare 2, Epic 3, Exotic 4, with Oddities that expand the board instead.
• Contact edges — how many of its cells touch other occupied cells. This is where adjacency bonuses come from.
• Anchor cell — the cell the pattern rotates around. Shields, movement cells and damage engines all behave differently depending on which hex is the anchor.

Two patterns with identical stats and different shapes are not interchangeable. A 3-cell L can wrap a corner and touch four neighbours; a 3-cell bar in the same place touches two. That is a 2× difference in adjacency income from the same rarity.

The four shapes you will actually use

Bar (1×3 / 1×4). Best value along an edge or a wall of the board. Cheap to place, terrible at wrapping corners, and the correct choice for stat-stick cells like plating.

L and hook. The adjacency winners. An L tucked into a corner touches the maximum number of neighbours for its footprint, which makes it the default shape for your damage engine.

Triangle (3 cells). Compact, leaves awkward gaps around it, works when you need to fill a hole in an existing cluster without spilling outside it.

Wide bloom (4+ cells). Exotic territory. It either becomes the build's centrepiece — Modular Construction turning one shield into six — or it eats a quarter of your board for a stat you did not need.

Place clusters, not cells

The board rewards contact, so the mental model is clusters, not slots.

1. Pick a corner or an edge as your damage corner and never put defence there.
2. Build the damage cluster outward from the anchor cell so each new pattern touches at least two existing cells.
3. Keep the defence lane on the opposite side, as a separate cluster that also touches itself.
4. Leave the middle free. Middle cells are the ones you will want at level 25 when a new Epic arrives, and they are the hardest to fill without breaking both clusters.

A build laid out this way reaches higher stat totals with the same drops than one where each upgrade was slotted wherever it fit at the time. The difference is not subtle — it is usually the gap between clearing threat 5 and dying in the second room.

Adjacency-lovers worth building around

Some cells explicitly want contact, and they should shape the whole layout:

• Slide Buffer pays out when cells are touching, and a slide build chains slides for movement. Put it in the middle of your largest cluster, never on the rim.
• Brittle Battery trades durability for output; it belongs in the damage corner where nothing defensive can be lost.
• Structural Survey and Scrap Repurposing convert board state into economy, so they want to sit where they touch the most cells you are keeping long-term.
• Boundary Incursion (an Oddity) expands the grid. Place it first when you get it — every later pattern gains from the extra board.

Rotate, then commit

The game has a rotation step: you are offered patterns and you choose. The order you take them in matters because later choices are shaped by the board you already built.

A rotation rule that works at every threat level: take the cell that completes a cluster, not the cell with the bigger number. A Rare that finishes a touching pair is worth more than an Epic that lands alone in the middle.

If a rotation offers nothing that touches your engine, take economy (Frantic Greed, Grenade Recycling) and keep the board clean rather than forcing a bad fit. Empty cells cost nothing; a badly placed Epic costs four cells and every adjacency they would have produced.

Infusion is pattern surgery

At player level 13 you can infuse an upgrade with another pattern. Since the 2.0.2 rescale, a larger pattern gives more stats than before and a smaller one takes away less, which finally makes infusion a normal part of building rather than a trap.

Use it to fix shape, not to chase rarity:

• Infuse a bar into an L when you need contact at a corner.
• Infuse a narrow cell into a wide one only on your main damage engine — that is where the multiplier compounds.
• Keep duplicate patterns of your engine cells in reserve from level 10 onward. Secret patterns from special missions are the highest-value infusion fodder in the game; do not spend them on fillers.

FAQ

Do upgrade patterns rotate or stay fixed? Each offer gives you fixed shapes to choose from. You choose the order and placement, so the same drop can be a corner piece in one run and a rim filler in the next.

What is the best shape for a damage cluster? An L or hook in a corner. It touches the most neighbours for its footprint, which maximises adjacency income from the cells you were going to take anyway.

Does placement affect infusion results? Infusion compares pattern size, not position. Position matters for adjacency; size matters for the infusion multiplier.

Can I undo a bad placement? Only by rebuilding. That is why the empty-cell rule matters — leaving a hole is recoverable, filling it with the wrong shape usually is not.
