If you're drawn to games that blend creativity, exploration, and sandbox-style engineering, you've likely heard of Space Engineers. Since its debut in 2013, the game by Keen Software House has become a cornerstone for lovers of open-world, space-focused construction games. Now, with the studio currently developing its sequel, Space Engineers 2, the question arises: how does this new installment measure up in its Early Access phase, and is it worth investing in yet?

A Fresh Start with a New Engine

At the heart of Space Engineers 2 lies the entirely new VRage 3 engine, which represents a significant commitment by Keen Software House to reimagine the core technical architecture of their game. Unlike the first game, which evolved gradually in Early Access over more than a decade, the sequel starts fresh, featuring entirely rebuilt planetary environments, volumetric clouds, dynamic weather systems, and terrain composed of voxels. This allows for unprecedented realism, as environments are not only visually stunning but interactable—mountains, valleys, and even water are designed to function realistically within the game world.

Speaking of water, the system is being designed as far more than just a visual flourish. Water in Space Engineers 2 behaves as a physical volume, meaning players can manipulate it to create functional elements like hydroelectric dams, boats, and even submarines. Though still in development, this promised interaction sets Space Engineers 2 apart from many other sandbox games.

However, this progress comes with its challenges. The engine is demanding on hardware, and performance can vary depending on system specs. While some users experience smooth 60 FPS gameplay, others face performance instability. The studio has acknowledged these issues, committing to optimization over time. A standout feature of the VRage 3 engine is its dedicated multi-core support—a major improvement over the first installment, where large-scale builds often lagged regardless of hardware capabilities.

What’s in Early Access Today

As Space Engineers 2 launched into Early Access in 2025, it came sparsely equipped but with the studio's clear intent to iteratively expand its systems. Currently, players can explore the Almagest system, which features two planets—Verdure and Chémique—each with their own unique moons, asteroid belts, and salvageable points of interest. Gameplay is limited to solo mode for now, with multiplayer capabilities scheduled to roll out incrementally, beginning with 4-player co-op by late 2026.

The survival mode walks players through essential systems, like ship construction and module management, a thoughtful design element particularly aimed at newcomers. On the other side of the spectrum, the creative mode allows unrestricted building, where the only constraints are player creativity. While the content is admittedly slimmer compared to the first game, this streamlined approach is welcoming for new players, offering just enough to discover at a reasonable pace.

The Core of Space Engineers: Construction

The very identity of Space Engineers lies in its emphasis on building—whether it’s ships, bases, or complex machines. Building mechanisms in the sequel have seen notable improvements, including the introduction of detail blocks that measure just 25 cm per side, a significant reduction from the 50 cm grid of the first game. This change unlocks an impressive level of customization, allowing players to design intricate and detailed creations.

For efficiency enthusiasts, the building mechanics also cater to optimization. Whether crafting mining ships for large-scale resource extraction or lightweight transporters to minimize fuel consumption, the game’s loop of design, test, and refine offers an engaging long-term challenge. The blueprint system also returns, enabling players to save and share their creations effortlessly via the Steam Workshop, fostering a thriving community of builders.

Bridging the Gap to the First Game

While Space Engineers 2 introduces advancements, it's clear that the transition from the original title will take time. The first game continues to receive updates, with recently added gameplay features like farming. Keen Software House anticipates porting these mechanics into the sequel gradually, creating a robust, cumulative experience over time. Recent updates for Space Engineers 2 have brought over iconic features like rotors and pistons and introduced improved physics for these systems. Functional weapons, an action bar for ship management, and dynamic weather effects have also been added to enrich early survival gameplay.

For fans of combat or automation, the upcoming patches provide even more reason to stick around. Wind turbines, sensors, control blocks, and more are on the horizon, building out the mechanical potential of player creations. The long-term goal remains clear: to retain the richness of Space Engineers 1 while layering it with the upgraded visuals, performance, and systems unique to the sequel.

The Future: Multiplayer, Narrative, and AI

Multiplayer is a glaring omission in the current build of Space Engineers 2. While the studio aims to roll out an initial co-op system by the end of 2026, larger multiplayer servers are part of their long-term vision. Additionally, a narrative campaign featuring interactive NPCs is on the roadmap, marking a significant shift from the sandbox-focused experience of the first game.

AI integration is another ambitious goal. With updates scheduled beyond 2026, Keen Software intends to revamp non-player interactions, creating a game world that feels lived-in while maintaining the sandbox flexibility central to Space Engineers’ identity.

Verdict: Who Should Play Right Now?

Space Engineers 2’s Early Access availability makes it both a work in progress and a unique entry point for new players. The streamlined content reduces the overwhelming feeling of diving into the massive feature set of the original game, allowing newcomers to familiarize themselves at a comfortable pace. For veterans of Space Engineers 1, however, the sequel may feel incomplete for now. Many are waiting for key systems like volumetric water, expanded multiplayer, and additional building elements.

Still, the incremental nature of updates has its advantages—players get to experience the game’s evolution firsthand, sharing feedback and witnessing new features as they’re introduced. At a current price point around $25, Space Engineers 2 also offers excellent value for those willing to invest in its ongoing development.

The DNA of the Space Engineers franchise remains intact: a game built for engineers, creators, and dreamers who see galaxies as canvases for their imagination. While there’s still a long road ahead, the foundations of something extraordinary are already in place.
