Space Train is a tactical arcade game where you pilot a cargo train across hostile space, delivering packages between distant stations. You're not on rails - navigate freely in any direction across a large 2D cosmos. Each station assigns your next destination. Plot a safe route through asteroid fields, or risk a direct path through enemy patrols. Three enemy types hunt you down: - Raiders dash aggressively - Interceptors strafe and dodge - Marauders fire spread volleys Your homing missiles reload slowly - make every shot count. Destroy enemies for bonus points. Upgrades scattered across the map change your capabilities: - Rapid Fire: auto-fires missiles - Magnet: pulls cargo and upgrades toward you - Time Slow: slows hazards and projectiles - Shield: defends from threats - Speed Boost: quick dash The cosmos shifts through different biomes with unique hazards - meteor showers, black holes, comet strikes, and drifting debris. Your minimap tracks stations, obstacles, pickups, and enemies for tactical planning. Controls Touch: drag to move, tap buttons to fire missiles or activate shield Keyboard (iPad/Mac): WASD movement, K to shoot, H for shield, B for boost Unlock new train skins as you improve. Progression is skill-based - learn enemy patterns, manage your upgrades, and survive longer deliveries across an unforgiving map.
