Devlog 41: Automation, Regional Progress, and Loot Physics on Mars

There’s a rhythm to building on Mars: some months are all show, others are about wiring up what’s underneath. This month was about connecting those wires - automation, regions, and enemy escalation - so that every new area feels distinct and every system supports the next.

⚙️ Automation: Machines That Work for You

Much of this month was spent improving the backbone of the game’s automation. Machines and containers now automatically handle their own input and output, letting resources flow between systems with minimal player intervention. This is a big step toward the fully functioning, player-driven supply chains that make large-scale defenses possible.

🧪 Item Pickup Performance: Stress-Testing at Scale

Sometimes the only way to be sure your code works is to try to break it. That’s why we decided to drop over 18,000 items in one spot, just to see what would happen. (Sorry, Mars.)

The result? A mountain of loot taller than most of our buildings, and a framerate that was still holding strong. Thanks to the pickup radius logic, items were instantly collected when running through it, leaving behind what can only be described as the world’s first player-carved tunnel of loot (no sources were checked while making this claim. No sunlight seen since the start of this project).

If you’ve ever wanted to clean up a mess so efficiently that you accidentally invent Martian mining, we’ve got you covered.

🗺️ Regional Systems: Distinct Frontiers, Unique Challenges

The world of Hostile Mars is no longer one giant base; it’s a network of distinct regions, each with unique play spaces, threats, and progression:

• Regional storage means every region manages its own resources, pushing players to adapt their strategies and logistics.

• Unique spawn points and enemy types are assigned per region, so every new territory introduces a different defensive and automation puzzle.

• Region-specific setups now include their own spawn points, power systems, and storage, providing a fresh tactical challenge in every zone.

Regions aren’t just cosmetic; they shape gameplay from the ground up, forcing creative solutions as players expand across Mars.

🪓 Spawn Systems: Designed for Player Agency and Escalation

After months of iteration, the enemy spawn system has been fully reworked to give players more control and to tie enemy escalation directly to automation and regional progression:

• Manual activation: In some cases, players choose which spawn points to activate and when. Each is tied to a unique bot type and activates escalating waves as you progress.

• FixedWaves and upgradesEach spawn point ramps up over five waves, maxing out at a fixed output. After reaching the cap, you can upgrade the spawn for higher-tier, more rewarding (and challenging) enemies.

• Strategic diversity: The order and types of spawn points you activate define the enemy composition and flow, so every region, and every playthrough, feels different.

• Automation integration: Some late-game spawn points require item input (manual or automated) to trigger waves, integrating your supply chains directly with the combat loop.

• Player pacing: You control the rate of escalation, letting you prep defenses and automation at your own pace, before choosing to trigger the next wave.

🛠️ Building the Build Mode UI

While much of the core systems work continued in the background, Hugo focused on updating the Build Mode UI to support all the new design changes. The goal is to make building more intuitive, responsive, and visually clear for players.

This month’s work centered on prototyping new interface elements and logic, still using programmer art, so the team can rapidly test different layouts and user flows. This hands-on approach is helping us define the player experience we want before finalizing the look and feel.

These efforts are setting the stage for a smoother, more satisfying Build Mode, where players can construct and manage complex bases with confidence and clarity.

🏗️ Design: Mars is No Longer a Monolith

With these changes, Hostile Mars is moving away from the old “one super-base” mindset. Instead, each region is a modular puzzle: its own power grid, automation backbone, and unique set of threats.

• Terrain, verticality, choke points, and hazards now push players to constantly rethink their builds.

• Facilities and points of interest reward exploration and clever engineering.

This approach keeps expansion fresh and meaningful, and gives every step across Mars a sense of progress and discovery.

🎨 Art: Enemies, Environments, and Atmosphere

• New Enemy: The Sawhead Niclas Halvarsson created an in-game version of the new “Sawhead” enemy, a bot built to cut into Mars.

  

• Concepts: Old Mars Bases Daysh provided concept art for possible mining operations, showing everything from large industrial complexes to smaller, more intimate sites.

🔭 Looking Ahead

The team is working toward a world where every region, every wave, and every upgrade feels deliberate and satisfying. The systems put in place now are all about giving players more agency, more variety, and more reasons to keep exploring.

Thanks for being with us through these foundational months.
