Monolith

Monolith is solo sci-fi skirmish game about plundering the depths of an immense arcology known as The Citadel and battling the minions of the cruel sentient intelligence imprisoned within. You control a team of three Remnants as they emerge from the wasteland to scour the city for relics, and lead their crusade to destroy the immortal machine once and for all. The game offers eighteen unique scenarios, nine different enemy types and three levels of increasing difficulty presented in a campaign that never unfolds the same way twice. Along your journey you will recover Fragments of the past to craft and upgrade your weapons, armour and cybernetic augmentations while resisting Corruption and attempting to complete objectives that will cause The Citadel's Collapse. It's designed for solo play, with quick resolutions, dynamic initiative and special abilities that can turn the tide of battle. It's miniatures agnostic, so any kind of sci-fi, cyberpunk or grimdark future collection will do, in terrain of any kind of urban hellscape. Have no fear. The Citadel must fall. —description from the designer
