Like I said, he's playing at too easy a level. My first time through I played on Normal and had no problems defeating anything in the game later on. So I upped the difficulty to Hard. And I definitely can't drop a Brute with a single shot at that level. Almost, but not quite.
And like I said I haven't touched a FPS game for at least 6-7 years so I am not very good at it. How difficult you set the game shouldn't be based on what other people do. Everyone is different. That is why they have adjustable difficulty.
I am not afraid to admit I am not the best at this game. I am only 19, and when I was still in school my mom wouldn't even let me play a game like james bond golden eye for N64. She really didn't want her son killing people lol.
A challenge can be fun, but if it is too hard it just becomes irritating, and we play games to have fun so then it would be pointless.
You are you and I am myself and we have different skill levels so you do it your way and I'll do it mine.
Now lets get back on topic shall we.
I think I'll go do the arlington library thing to get the survival guide done and then do the quest for Blackhawk. After that I think I will do the main quest up to doing 3 dog's quest and get the Xualong Assault Rifle mini quest done while at the museum of technology. Then maybe I'll get Reilly's Rangers and Stealing Independence done to get syndey's SMG.
