Plant Squad

Plant Squad is a merge-flavoured tower defence: drop plants on a grid, drag the same kinds together to mutate them into stronger species, and hold the line as the undead bring heavier units against your lanes.

🌱 Plant Squad: Fuse to Survive

Plant Squad takes the familiar shape of a lane defence — a grid, a garden, waves of the undead — and makes one change that alters how you play it. You do not upgrade a plant by spending money on it. You upgrade it by sacrificing another plant of the same kind to it.

That single mechanic turns the board into a resource problem. Every fusion is one fewer body on the grid, so the strongest plant you can build is also the one that leaves the widest hole in your line. Winning is a matter of deciding, wave by wave, when a mutation is worth the gap it opens.

🎮 How to Play

1. Drag a plant onto the grid. It starts shooting down its lane immediately — no activation, no cooldown to manage.
2. Match to mutate. Drop an identical plant of the same level on top of it and the pair become one stronger species.
3. Watch the front. Enemies walk in from the edge, so the first row is where the work happens and an empty square there is a free pass.
4. Rebuild between waves. Every fusion spends a plant, which means a defence that was solid two waves ago may now be a corridor.

Controls are mouse-only: pick up, drag, drop.

🌿 Reading the Grid

Placement matters as much as the plants themselves. Slow, heavy hitters belong at the back, where they get more shots before anything reaches them, while fast-firing plants want the front row so the quickest enemies meet fire before they can close the distance. Fused plants throw longer and harder, which makes the back row the natural home for your best mutation — it covers more of the runway.

The other half of it is coverage: a lane with four ordinary plants firing constantly usually out-damages a lane with one monster plant and three empty squares. The undead do not care how impressive your best unit is if the path to the garden is unguarded.

🧟 The Waves

Each wave arrives with better equipment than the last. Early enemies are slow and single-lane; later ones throw heavier and better-armoured units at you, enough that the answer is not one perfect plant but a re-balanced grid. That escalation is what keeps the merge decision live right to the end: the plant you fused in wave three may be exactly the one you need to break apart with new growth in wave eight.

🎯 Tips for a Stable Line

• Stay wide early. Spend the first waves building coverage rather than a single champion.
• Fuse the lanes you can still cover. Mutating a plant on a lane with backup is safe; mutating your only defence on an exposed lane is not.
• Keep your big plant behind the small ones. Range is wasted if it sits at the front where enemies meet it first.
• Rebuild before a wave, not during it. The undead will not pause while you rearrange the garden.
• Watch which lane leaks, not your total score. The run ends on the lane you forgot, and that lane is always the one you fused out.
