The new open beta v0.2.2.c of "Heat Death: Survival Train Demo" is now available! Download it right now on Steam and dive into the thrilling survival experience that awaits you. Here’s what’s new:

• Airborne Scout Drones (New Enemy Type): The old scout drones have been replaced with new airborne drones that are faster and more challenging to overcome.
• Rapid Burst (New Train Weapon): The Rapid Burst weapon uses train power instead of ammo. This weapon is designed to defend the train against the new drones.
• Heat as a Resource: This community-suggested system now physically propagates heat on the train, meaning you must consider structural module insulation (e.g., walls are better insulators than windows). Certain modules (like engines) will produce small amounts of heat, but if you keep the doors open during a storm, all of it will dissipate.
• Physical Train: Train physics is now more realistic. Each module has mass, and as you build them, the train becomes heavier, reducing its acceleration. Storms will also change the train's air drag, reducing its top speed during storms.
• Fall Damage: You'll now take fall damage. Please let us know how this affects your play style.
• Blueprint as a Resource: By popular demand, you can now unlock the modules you want instead of relying on random unlocks! Blueprints are now a collectible resource in your inventory.
• New Structure Unlocking System: Structural modules are no longer available from the start. You’ll need to reach train stations to unlock them.
• Fission Reactor (New Module): This powerful module generates energy using fuel. However, it’s radioactive while in operation and produces highly radioactive waste that must be stored or disposed of safely!
• Module Deterioration: Modules like the Engine, Dynamo, and Fission Reactor will now wear down over time, adding a new challenge to maintaining your train.
• Difficulty Levels and Game Balance: We’ve introduced new difficulty levels and rebalanced the game accordingly. You can adjust the difficulty level at any time during your adventure.
• Other Changes, Bug Fixes, and Tweaks
