The SteamWorld Heist series is a spin-off of the SteamWorld franchise, focusing on turn-based tactical gameplay where players manually aim their ricocheting shots. The series includes the original SteamWorld Heist, its Ultimate Edition port, and the sequel SteamWorld Heist II. Players command a crew of steam-driven robots navigating side-scrolling space and maritime environments.
Developed by Image & Form, this branch of the franchise expanded the fictional universe's lore. Following its initial launch, the debut entry saw wider distribution with
Steamworld Heist (2018) and
Steamworld Heist (2020) releasing across multiple platforms, alongside the feature-complete
SteamWorld Heist: Ultimate Edition (2020). These releases showcased procedural level generation and a distinct soundtrack composed by the real-world steampunk band Steam Powered Giraffe, who also appeared as in-game entertainers.
The property expanded with
SteamWorld Heist II (2024), which introduced an interactive overworld map for vessel navigation and a flexible job system allowing players to customize their crew's abilities and weapons. Thunderful Games continued supporting the sequel with subsequent versions, including
SteamWorld Heist II (2025),
SteamWorld Heist II (2025), and
SteamWorld Heist II (2025) to accommodate additional platforms. The series is highly regarded for its art design, character writing, and the integration of physics-based projectile trajectories into grid-free movement systems.
