When it comes to fortification, tunnels are a must. Not just any tunnel will do, however. No, no. We're talking top-of-the-line, secret, underground bunkers that will keep you safe from the hordes of enemy soldiers.
Here's a few techniques you might find useful when building your own secret tunnel system:
- Use a mix of reinforced steel and concrete for maximum durability.
- Install a state-of-the-art ventilation system to keep the air fresh.
- Consider installing a hidden entrance, like a fake bookshelf or something.
- Don't forget to stock up on snacks!
