For What Remains is a series of three skirmish-level strategy games set in a post-apocalyptic near future:

• Streets of Ruin
• Blood on the Rails
• Out of the Basement

Blood on the Rails includes the factions Echo and Soldiers of Light, and is part of the Blood on the Rails campaign. Echo is a faction guided by a secret group of people with psychic powers, while the Soldiers of Light are humans who believe that humanity's downfall came from dependence on technology.

The game is designed for 2 players in a competitive format or for solo play, and each set can be played standalone or in combination with other sets to form a larger narrative. Players control characters from one of the six factions in the game.

There are two modes of play in For What Remains: skirmishes and campaigns. Skirmishes are standalone games played for a single victory, with no lasting consequences. Campaigns are a series of skirmishes linked together to form a larger narrative.

For What Remains is a scenario-driven game.
