In the game Robbery FPI bank, you are a bank robber, and not the luckiest one at that. You intended to commit a quiet, silent robbery, but as soon as you entered the bank, you ran into security. You will have to shoot back, and then you need to look for the keys to the vault, open safes and look for valuables and money. There are guards waiting around almost every corner, and your ammo supply is limited, so you can't carry an entire arsenal with you. Therefore, try to hide more and look for workarounds. And shoot only in extreme cases, when it directly threatens your life in Robbery FPI bank.
