Players who enjoy a dark and gritty world in their grand strategy games should give the following titles a try.

While many colony simulators are more focused on granular mechanics and deep gameplay than story, theme, or tone, a few projects manage to be thematic. Of these, even fewer take on a truly dark tone. However, some colony simulators embrace their naturally dark themes.

This somewhat obscure release from 2016 is a dark, post-apocalyptic colony simulator packed with demons and dark magic. Judgment's gameplay feels like a lighter, more accessible version of RimWorld, but takes on a darker, apocalyptic tone.

Judgment may come across as almost over-the-top darkness with its Hellspawn demon enemies and occasional voiceover, but this B-movie darkness is arguably what makes it so distinct. With its gritty setting and downtrodden characters, as well as its focus on constant scavenging and defense against horrific creatures, Judgment is perfect for players who enjoy over-the-top darkness.

From the developers behind This War Of Mine, Frostpunk offers a post-apocalyptic colony-management experience of building a city in a frozen world. Players will have to contend with the discontent, starvation, and illness of their colonists as they expand their colony in an attempt to survive.

Frostpunk can be brutal, and extremely challenging at times. However, what makes it so dark is its stark focus on gray morality. Frostpunk constantly asks players to make tough, even cruel decisions for their colonists, most of which force them to face dark realities.

While Kenshi may not market itself as a colony simulator, and it can certainly be played in a multitude of ways, the late-game of Kenshi can often evolve into a combination of base-building and colony management. This often happens after the player has become strong enough to defend themselves, has amassed a small fortune, and usually having gathered an abundance of party members.

Kenshi is a wonderfully immersive open-world game, but it's not kind to newcomers. Here's how to survive the first few days in the desert.

With a wealth of currency and a small army in tow, players will often need to build a base to act as their headquarters. While Kenshi's base-building may not be as fluid as more focused colony sims, and the gameplay is much more focused on micromanagement and automation, its unique dark-fantasy setting and brutal world make Kenshi a great choice for fans of darker experiences.

This wildly popular Roguelite indie game features action Roguelite gameplay that tasks players with crawling through dangerous dungeons full of enemies. However, outside of these dungeons, players spend their time expanding and managing a dark cult.

Cult of the Lamb may have a cute aesthetic with its anthropomorphized animals and hand-drawn art style, but this is in stark contrast to its gameplay. Cult of the Lamb may not be the darkest colony sim out there, as its tongue is firmly in its cheek, but the cult-building theme and gameplay mechanics surrounding dark rituals and ritual sacrifice make Cult of the Lamb a decidedly dark experience.

RimWorld is arguably responsible for the modern popularity of the colony sim genre. Since its release on Steam in 2018, RimWorld has evolved with updates and DLC to become not only one of the best colony simulators, but perhaps one of the darkest.

7 Most Downloaded RimWorld Mods

RimWorld may be one of the most complex colony sims on the market, but these extremely popular mods iron out the rough edges for a better experience.

While RimWorld may not appear particularly dark or gritty on the surface, the freedom it gives players can lead to some morally gray situations. RimWorld doesn't shy away from dark themes and gameplay mechanics surrounding drugs, slavery, and the removal (and selling) of vital organs. RimWorld never tells the player what they're doing is wrong, and that's perhaps the darkest thing about it.

This dark and gritty colony survival game tasks players with managing and protecting a group of downtrodden civilians in a war-torn world. This war-ravaged setting is packed with dark stories, characters, and heartbreaking events, making This War of Mine consistently dark.

This War of Minecan be pretty emotional, thanks in large part to its theme and tone. Similar to games such as Frostpunk (from the same developer), This War of Mine also frequently asks players to make tough decisions, driving home the game's dark theme and tying it into the gameplay.
