Jam Key Themes

• Teamwork.
• Enemies are humans!
• Ancient secrets (extinct civilizations, forgotten gods, secrets of planets).
• Science fiction (any hardness).

Each submission should use at least one key theme from the list. Use it as you like (literally or interpreted), but it would be great to put them close to your central theme or inside one of your mechanics. You would get imaginary cookies for using all of them!
