In the middle of my second play through. I decided this time to take it easy on the bow and try using some of the more standard fair weapons. I saved up my scrap and completely upgraded the assault rifle as far as it could go during the part where you get the grenade launcher. Couple that with rifle mastery, I was having a blast running up to bad guys, shooting them in the leg and having Lara unload a whole clip from their stomach all the way to their head. Not even Rambo was this brutal!
