I have never collected every bobble-head in the game ever. I'd seriously need a guide for them all, lol. Also, I am trying to get very high in melee this time around. I never used those weapons that much. It's tough when fighting enemies who use guns all the time.. But I feel like you can easily lure an enemy out 1 by 1. And before doing so you can damage them by setting traps with mines. :3
