~Tips~
1. Don't use the flashlight and alot of the monsters will ignore you but some will still attack though.. most of the game is not that dark so you shouldnt need it
2. Run.. unless your going for the 200 kill prize or the other enemy related prizes then just run specially when out in the street
3. Look everywhere!! this game has tons of items and weapons so look everywhere
4. i don't know if its a stamina glitch or not but if just hold down the run button they won't catch you... even when your running really slow.. i never got caught
