Motherboard Under Attack

Motherboard Under Attack is a turn-based tower defense game in which you protect a computer’s motherboard from waves of viruses. Collect solder, the in-game currency, and place electronic components as defense towers to stop viruses from infecting the processor. Manage tower positions and upgrades as the waves grow stronger.

Defend the motherboard

Each tower is based on a real electronic component and has a distinct function:

• Diode: fires quickly at ground viruses.
• Capacitor: deals high damage with a slow-firing cannon.
• Inductor: slows viruses with a continuous, low-damage laser.
• Transistor: provides effective air defense.
• Resistor: slows viruses but loses durability.
• Fuse: acts as a powerful explosive trap.
• Oscillator: generates more solder.

Face the viruses

The invading viruses have different abilities and attack patterns:

• Common Virus: fast and numerous.
• Spyware: flies but is fragile.
• Adware: flies and damages towers.
• Worm: infects towers and temporarily disables them.
• Trojan: a ground-based tank that splits when destroyed.
• Botnet: a massive tank boss that attacks towers.

Upgrade your towers

Spend solder to upgrade towers and collect batteries to unlock Bronze, Silver and Gold levels. Each tower changes visually and gains new powers as it is upgraded.

Progress through stages

Unlock stages based on your performance. Reaching wave 25 of stage 1 unlocks stage 2, and each stage adds new challenges and unique objectives. The game has a retro electronic look, an immersive soundtrack and progressively challenging stages.
