20 Strong – Solar Sentinels is a solo science‑fiction tactical game set in a dark future where humanity stands on the brink of destruction due to an invasive alien species known as the Horde. These “moon bugs” have constructed a base beneath the surface of the Moon and are preparing a final assault on Earth. The planet’s only defense is an elite group of warriors called the Solar Sentinels, who carry out a desperate attack on the enemy stronghold using the power of solar energy.

The player takes on the role of one of the Sentinels and faces a sequence of dangerous enemies, events, and challenges, culminating in a decisive confrontation with a powerful final foe, creating a highly cinematic and tense science‑fiction experience.

20 Strong is a modular solo card‑and‑dice game system designed for fast yet content‑rich play sessions.

The player uses a set of 20 special dice to try to score enough “hits” to overcome individual challenges. Each card represents an enemy or a unique challenge that requires careful decision‑making—whether to risk rolling more dice or to play more cautiously. Three key attributes (health, strategy, and recovery) determine how many dice can be reused, how often rerolls are available, and how long the player can withstand enemy pressure. Failing to overcome a challenge results in taking damage, but the game continues until the player is reduced to zero health.

Solar Sentinels serves as the core set of the 20 Strong system, meaning the same core rules can later be used with other thematic sets from the same game family.

20 Strong – Solar Sentinels Core Set is an excellent choice for players seeking a fast, tense, and tactical solo science‑fiction experience in a small box. ☀️🚀
