Humanity pushed too far into the outer systems. Now the frontier burns with pirates, alien threats, desperate colonies, and ancient mysteries waiting beyond the edge of known space. Cosmic Frontiers is a gritty turn-based sci-fi tactical RPG where you command a crew of frontier survivors across dangerous worlds, deadly missions, and unforgiving space conflicts.
The Core Concept
Cosmic Frontiers: Episode Zero is a cooperative 2D Sci-Fi survival RPG. It blends hex-based overworld exploration, intense resource management, and grid-based tactical combat. Designed with a tabletop-RPG feel, 1-4 players share command of a 4-hero expeditionary squad trying to survive, scavenge, research, and ultimately signal for extraction on the hostile, uncharted world of Xylos-7.
Feature Summary
🌍 Overworld Exploration & Survival
Hex-Based Map & Fog of War: Dynamic chunking map with hidden points of interest, resource deposits, and anomalies.
Resource Economy: Managing Water, Fuel, and character Comfort. Movement costs are calculated on the fly with pathfinding UI that warns players of fatal resource depletion before they move.
Frictionless Scavenging: Auto-collection of map resource deposits upon traversal, speeding up exploration.
Deployable Infrastructure: Players can craft and place Shelters, Radar Towers, Teleporters, Storage Crates, and rideable Rovers directly onto the world map.
Dynamic Weather: Procedural sandstorms that reduce visibility, accelerate comfort drain, and damage equipment.
⚔️ Tactical Turn-Based Combat
Grid-Based Arenas: Seamless transitions from the overworld into turn-based tactical combat (Dungeons, Ambushes, and Bosses).
Deep Mechanics: Action Point (AP) economy, Line of Sight, elemental damage, status effects (poison, stun), and environmental hazards (explosive barrels, toxic vents).
Epic Boss Encounters: Cinematic Larry Elmore-style panoramic backgrounds, multi-phase Boss AI (like the Ancient Guardian's orbital lasers), and a highly polished, stylized Boss Defeat loot-drop sequence.
🤝 Tabletop-Style Multiplayer
InstantDB Synchronization: Real-time sync for 1-4 players. Players can trade items, heal each other, and cooperatively vote on dungeon paths.
Shared Squad Control: Players seamlessly divvy up the 4 squad members in the Lobby.
Self-Healing State: Robust packet-loss recovery and reconnection logic ensures dropped players instantly catch up on missed quests, map reveals, and inventory changes.
