Immune Commander

Command the body's defenses

Bacteria are pouring through a scraped knee. Viruses are hijacking cells. A biofilm fortress is rising in the wound. You are a single dendritic cell — the messenger between innate and adaptive immunity — and the battle depends on where you lead your troops next.

Key features

• Lead, don't micromanage — stand near a blood vessel to recruit neutrophils and monocytes, then charge pathogens with a single command. Shift + direction charges on desktop.
  
• Real immune strategy — touch a pathogen to take a sample, carry it to the lymph node, and B cells build specific antibodies. Capsule bacteria, viruses hiding inside cells and fungi each need a different answer.
  
• A whole life as a roguelike — follow one patient through 8 life stages, from a toddler's scraped knee to old-age pneumonia. Every node on the organ map is a battle; pick immune cards, growth choices and vaccines along the way.
  
• Outposts and tower defense — post squads at entry points; firebases, depots and watchposts level up as they fight.
  
• Bosses with a mechanism — break a staph biofilm, out-adapt a mutating flu, survive sepsis.
  
• 26 challenge levels, including acute and major disease scenarios, plus Endless Survival: how long can a healthy body hold out?
  
• Immune Codex — 28 illustrated entries explaining how every cell and molecule really works, ready to copy and share.
  
• 73 achievements, 5 difficulty levels, on-screen hints you can switch off, adjustable text size, and full support for 13 languages.

Easy to learn, surprisingly deep — and you will never look at a fever the same way again.
