Toxic Frontier is a card-based city-builder for a poisoned world
Mint Gate Games showed its roguelike city-builder at Tokyo Game Show, where 40 reactive hex tiles and a deck of cards are the tools for reclaiming a contaminated world.
At a glance
What it is: a roguelike, card-based city-builder played across a hex grid in a post-nuclear wasteland. Developer and publisher: Mint Gate Games and Meteorbyte Studios. Release window: Q1 2027. Platforms: PC, with gamepad and Steam Deck support. Price: not yet announced.
A city-builder that deals you a hand
Toxic Frontier was revealed during the PC Gaming Show Tokyo Direct at Tokyo Game Show 2026, and the pitch is a hybrid rather than a straight city-builder. Players expand a settlement from a single hex tile by deploying cards, and the tiles they place react to whatever ends up beside them. The store listing calls the interaction between those two systems a fusion, and it is the hook the game is built around: the deck decides what you can build, the grid decides what it is worth.
Both of the developers' public descriptions of the game lean on the same idea. The publisher describes reclaiming a barren world from extreme contamination; the store page describes forging a path of purity from a humble solitary hex tile to a sprawling post-nuclear civilisation, and warns players not to run out of cards.
What is actually in the build
The announced feature list is specific. There are three ruined post-apocalyptic biomes, each with its own quests, mechanics and hostile conditions. There are 40 tiles to place, and each one carries its own effects. There are 40-plus cards to unlock and collect, and progressively more complex synergies between them to find. Four game modes are planned, with two different endings.
Presentation is being handled with unusual care for a reveal. The soundtrack is by Nikorem, and both gamepad and Steam Deck support are listed from the start, which is a reasonable signal for a grid game that will be played in long sessions. The release window is Q1 2027, with no date inside it, no price and no word on whether a demo will appear first.
Who is building it
Toxic Frontier is being developed by Mint Gate Games and published by Meteorbyte Studios, whose announcement closed with the studio's own character: a sign-off thanking readers and wishing them a great week. It is a small-team project in a genre where small teams have thrived, because tile-placement roguelikes live on the strength of their systems rather than their budgets.
Our opinion
The pitch is doing something smarter than it first appears. Most city-builders ask players to optimise, and most roguelikes ask them to gamble; here the gamble is the optimisation, because the card you must play this turn decides which tile earns its keep, and the tile you placed two turns ago decides whether that card is any good. That tension is genuinely difficult to tune and easy to get badly wrong, and three biomes is a modest amount of content to prove it in. The thing to watch will be whether the reactive tiles create decisions or merely combos to memorise, because a grid where everything answers everything is thrilling for two runs and exhausting by the twentieth. Meteorbyte and Mint Gate have given themselves until Q1 2027 to answer that, and the honesty of a 40-tile, 40-card scope suggests they know the question matters more than the count.
