Earth’s future is bleak. Despite harnessing the sun's power and siphoning plasma to advance technologically by leaps and bounds, the world faces an existential-level threat in the Horde. This encroaching alien species has set up a base beneath the surface of Earth’s moon, and these destructive moon bugs are preparing a final invasion to wipe out humanity.

The only thing standing between Earth and oblivion is a beleaguered fighting force known as the Solar Sentinels. Wielding the power of the sun and embarking on a last-ditch assault of the Horde’s lunar base, these brave Sentinels hope a surprise attack might destroy the Horde before it’s too late.

Solar Sentinels is a new property debuting in the 20 Strong game system, featuring a squad of stellar warriors fighting off an alien invasion. Players will select their sentinel and choose each round between one of three face-up opponents. They will deploy units to dispatch their enemies and collect rewards on their way to take down the alien leaders at the source of the invasion.

This is great solo game. Still looking for a few additional alpha approvals. Give it a try!

just did a play through for the German translation, there there where are some incoherent wordings in the Ability descriptions, and also 1 translation error of "Goremoth" reward... in German it doesnt state that you have to exhaust a die to use this ability!

1 more Error (or atleast i see it as one):
i killed "Flesh Locust" with the ability of "Gutterfly" and i still had to banish my strongest Die... does that only count when i defeat it with dice?

Translation questions should go in the translation forum. Even as a developer, I have no access to update translations.

For gameplay, visit the 20S: Solar Sentinels forum. Lots of excited players eager to help.
