About
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.
