Control three gas valves inside a volcanic foundry. Manage sulfur, steam, and ash ratios while pressure climbs. Handle seized valves, coupling leaks, and surges during four shift types: Steady, Unstable, Meltdown, and Inferno.

Explosive Tension simulates valve management in a Victorian-era foundry built inside an active volcano. Your console controls three gas lines feeding a high-pressure furnace system. Each valve wheel responds with realistic physics: swipe right to open flow, left to restrict it. The pressure gauge monitors total system load, climbing whenever valves stay open.
Orders arrive constantly, demanding precise ratios of sulfur, steam, and ash. Sulfur settles slowly and holds steady. Steam reacts instantly but drains fast. Ash accumulates unpredictably and resists reduction. In Inferno mode, slag enters the system and cannot be purged, forcing continuous compensation across other gases.
Failures cascade without warning. A coupling leak forces manual cranking. Dark sensors hide readings behind question marks. Creeping spindles open valves automatically. Surges force-feed gas until you triple-tap to cut the line. The repair board descends mid-shift, demanding fixes while orders continue. Every decision compounds.
Swipe valve wheels left to close, right to open. Each gas responds with unique physics. Sulfur stabilizes slowly. Steam drains fast. Ash resists reduction. Watch chamber indicators glow as mixtures change.
Open valves raise system pressure. Operate above 60% for 1.5× payment. Push above 75% for 2× rewards. Hit redline and the system breaches, ending your shift immediately. Risk versus reward at every moment.
Seized valves lock mid-shift. Couplings leak until cranked tight. Sensors go dark, hiding critical readings. Spindles creep open automatically. Surges force-feed gas requiring rapid triple-tap cuts. Complexity scales relentlessly.
Flip breakers, hold blown fuses, crank loose couplings while orders keep arriving. The repair board descends without pausing gameplay. Fix equipment under pressure or watch tolerances slip as faults multiply across systems.
STEADY introduces core mechanics with stable gas behavior. UNSTABLE adds equipment faults and tighter tolerances. MELTDOWN brings rapid order changes and cascading failures. INFERNO introduces slag that cannot be purged.
One persistent score across all sessions. Orders arrive continuously with progressively narrower tolerances. No levels, no completion screen. Only the question: how long can you maintain control before pressure wins?
