🎯 The mission
Stop the contaminant waves before they drain your Core. Survive every wave of a sector to advance; lose all Core health and the sector fails.
🔬 Energy through chemistry
The Research console shows AQA Chemistry questions. Every correct answer generates ⚡ energy — your build currency. Build a correct streak for a bigger bonus. Wrong answers earn nothing and briefly lock the console.
🛡️ Building & towers
- Pick a tower from the build bar (each shows its energy cost).
- Click a glowing node on the map to place it.
- Click an existing tower to upgrade it (if you can afford it).
- Towers auto-target the leading enemy in range.
🌊 Waves
Press Start wave when ready (starting early gives a small energy bonus). Tougher enemies and bosses appear in later waves and sectors.
🏅 Scoring & the badge
Score comes from enemies purified, waves cleared and answer accuracy. Completing the campaign marks the resource complete on your dashboard and earns the Core Guardian badge.
👩🏫 For teachers & parents
Pure AQA-aligned retrieval practice (formulae, balancing, acids & bases, the periodic table, ions & bonding) wrapped in a strategy game. Foundation / Higher / Triple tiers scale the questions.
