Yea, thats stupid. But think how simple would be the killing from the distance if the enemy didnt know where the shoots came from. Just try to: 1. use suppressor 2. shoot the enemy not visible to others first only when other enemy will find the body, the alarm will be made.
Quite likely none of the Devs has ever been shot at; let alone with a suppressed weapon [which is supposed to make it difficult for the targets to tell where it came from :lol:]. I could fix that for them; before they make the next game. ;)
