How to Play Silicon Invasion

Chapter 1 of Silicon Descent. Hold the homestead while the invasion escalates from dust to matriarch.

Enemies march from the top of the field. Clear them before they reach you. Finish a wave to earn points, unlock gear, and open the Power-Ups popup before the next round.

Aim, towers, and the shop

Aim with the mouse and hold fire. Swap weapons when armor shrugs off lighter guns. Drop unlocked defense towers into free slots along the bottom center. Between waves, spend points in the shop without leaving the run. Restart begins again from Act I. Retry resumes from the wave you failed, and saving that progress requires signing in.

The Five Acts

The campaign is told in five acts. Each act teaches the invaders a new part of the farm.

Act I · Silicon Dust

The first forms drift through the fields. Orbs. Triangles. Rabbits. Ducks. Even the rooster. The farm is being scanned. This is the warm-up and the first loadout window: learn the aim, earn early points, and place the first towers before the scan turns serious.

Act II · Shadows in the Pen

The silicon spreads into the pasture, the pigpen, and the barn. Sheep harden into hex shapes. Pigs return as armored blocks. Cats and dogs move with metal in their bones. Heavier enemies may resist LMG fire. Use HMG weapons to break their armor before they overrun the pens.

Act III · Iron Hooves, Starlight Edge

Cows and horses return as silicon giants, one built to crush the line and the other to break through it. Star-shaped elites rise from overlapping scans. Cattle and horses can shrug off LMG fire and resist sustained HMG fire. Use sniper rifles or anti-materiel weapons to pierce their plating.

Act IV · The Matriarch at the Door

The tide surges. Behind the herds, a matriarch node rises. Break it before the lamps go out. Focus fire, keep towers alive, and clear the fodder so the matriarch cannot hide in the pack.

The matriarch has reached the door. Peak density meets it at full strength. Clear the chapter, or keep fighting when the scan refuses to end.

Finale · The Scan Unfinished

The matriarch fractures, and the scan does not end. Silicon has memorized every shape on this farm. Endless pressure after the story beats keeps every remembered form in the tide, so survival becomes a score and a stance.

Weapons and Towers

• Rifle and LMG: the early-act guns, before armor shows up.
• HMG: the answer when heavier enemies shrug off lighter fire.
• Sniper and pierce weapons: for cattle, horses, and plating that resists sustained HMG fire.
• Sentinel Tower, Fire Node, Heavy Fortress, Sniper Tower, and Piercing Tower: unlocked across waves and placed in bottom-center slots as backup, not as a separate mode.
• Ammo is limited, so swap when the current gun stops mattering.

FAQ

When can you buy upgrades?

Between waves, in the shop, without leaving the run. A finished wave also opens the Power-Ups popup.

What is the difference between Restart and Retry?

Restart begins at Act I. Retry resumes from the wave you failed, once progress is saved on an account.
