Cost Exchange

You are the duty officer on an air-defence console. Contacts appear on the scope. You do not know what they are. Query IFF, wait three seconds, then read the returned data — speed, altitude, radar cross section — and INFER the threat yourself. The game never labels it for you. Then the real decision: which weapon? An IR missile costs $150k. A radar missile costs $350k. CIWS costs $5k. The laser is free but needs time you may not have. Fire the expensive one at a cheap drone and you win the engagement while losing the operation. A leaker that reaches the centre damages a facility. Lose enough facilities and the operation is over — no matter how much money is left in the vault. • Infer, don't be told — no automatic threat labels, ever • Four weapons with real trade-offs in range, cost and reload • Ammunition economy: every shot is a decision you pay for • Graded S to F on five criteria, with hard caps for downing a friendly • DAILY OPERATION — the same operation for everyone, one attempt a day • FREE OPERATIONS — endless seeded operations across four difficulty tiers No ads. No energy timers. No in-app purchases. Everything is unlocked. iPhone and iPad.
