I have no problem with those things,replayed the game twice already but,
Max Payne 3 has the same problem like Halo 4,devs kinda went overboard with encounter rate.Max Payne 3 has all those clues but they serve no purpose because game just throws tons of enemies at you.Room after room,area after area---you have just one goal,obliterate everything.There is no like uh tons of guys in this room maybe I should try some alternate approach.I doesn't help that enemies have psychic powers and spot you instantly after you pop from cover.
My favorite part is when you get a silencer but you apparently can't make silent killing.There are two instances in the game like that so if somebody managed not to alert others,please let me know.
