The Last Fortress: 100-Day Defense

"Commander, where shall we begin?"

This is a 100-day survival defense of the isolated Grey Gate Citadel.
You will become the Commander, recruit mercenaries, equip them, and lead your forces against the encroaching enemy.

⚔️ 10 Invasions in Total
The first invasion is on Day 5, and the last on Day 100. The preparation time between invasions gradually increases. Equip your mercenaries and gear up for the next assault.

🛡️ Prepare Yourself, Battle Automatically
Set your deployment and attack priorities, as well as treatment and retreat conditions, and the battle will proceed according to your strategy. When critical decisions are needed, such as an unexpected breakthrough or rescuing a comrade, the battle will pause and await your command.

🗡️ Recruitment and Spoils
Recruit new mercenaries and equip them with weapons obtained from defeating enemies. Mercenaries, weapons, and enemies range in rarity from common to legendary.

⌛ Limited Preparation Time
During preparation days, the next day will automatically begin after 3 turns. Recruitment, reinforcement, exploration, and rest can only be done once per day. Simply checking status or asking about rules does not consume turns.

🏰 A Story with an End
You immediately lose if the Commander dies or the Citadel is destroyed. Successfully defending on the 100th day marks the survival ending.

To start, try commands like "Show me available mercenaries to recruit" or "Tell me the cost to reinforce the Citadel." You can issue commands freely beyond the suggested options.
