BULK is out on Steam, turning a pile of cards into a dark-fantasy money machine
BULK launched on Steam on September 3 with a familiar incremental promise hidden inside a much stranger interface. Numbers still need to go up. The difference is that players are standing inside a dark-fantasy factory, physically grabbing cards from a conveyor belt and feeding them through machines to make that happen.
By Kader BULK 
Carlos “Monty” Montamarta developed and published BULK as a solo project. He says the game took roughly a year to build and is his second release as an independent developer.
The full game is now available for Windows through Steam, with a 10% launch discount running through September 10.
The spreadsheet has been replaced by a workbench
Cards arrive on a conveyor belt. Players pick them up, sort them and use a magical mixing device to combine them into higher ranks. Better cards sell for more gold.
That gold is immediately recycled into production. Conveyor speed, card rarity, output volume and new machinery can all be upgraded, gradually increasing the value and speed of each cycle.
The mathematics are recognizable incremental-game mathematics, but BULK makes the process unusually tangible. Cards occupy real space on the table, upgrades exist inside the factory and interactions are presented diegetically rather than primarily through conventional menus.
Automation arrives without completely replacing the player
Early progression requires direct handling. Later systems begin automating parts of the production chain, including selling and other repetitive tasks.
Montamarta has described this as a deliberate response to an incremental-game pattern he dislikes: clicking manually for a few minutes before the game effectively becomes pure idle automation.
BULK keeps some physical involvement while the machinery expands. The setting makes the routine stranger still, surrounding the economy with pipes, runes and medieval dark-fantasy imagery.
A free demo has been collecting feedback since 2025
The Steam demo launched in December 2025 and contains the core card-mixing loop, tool upgrades and a smaller progression target built around earning enough money to buy freedom.
By the full game's launch window, roughly 96% of its approximately 30 user reviews were positive.
The commercial version extends that structure with later upgrades, more automation, hidden lore and additional secrets inside the factory.
The first post-launch fixes are already being prepared
Montamarta says he has been collecting bug reports since release and expects the first update around the week following launch.
Planned work includes optimization improvements, fixes for settings that fail to carry between games, localization corrections and smaller bugs.
One less straightforward issue involves reports of constant camera movement for some players, which the developer says is more complicated to resolve.
The first Steam response is small but positive
By September 5, the full game had 25 Steam user reviews with an 80% positive rating. Two days after launch, that sample is far too small to treat as a settled reception.
The pitch is much clearer. BULK is aimed at players who enjoy optimization, automation and escalating numbers but still want to physically interact with the system after the factory begins doing some of the work itself.
Minimum requirements list Windows 10, 2GB of RAM, a GeForce GTX 1060 and 1GB of storage. Steam Deck compatibility is still listed as unknown.
