Grimdark Future is a free to play tabletop miniature wargame created by One Page Rules.

It is inspired by Warhammer 40,000 by Games Workshop, but designed to have simplified rules for increased ease and speed of gameplay.

[1][2] The game's rules also contain small paper tokens that may be used in place of models.

One Page Rules has been praised for its ease of gameplay, and has been called "perfect for casual gaming".

[5] Despite this, the game has been criticized as overly derivative of Warhammer 40,000 in terms of aesthetics, with one reviewer describing it as a "store brand version".
