ok... i took some of my time to give you guys some tips about some stages in this game, if you see a whitch...... scream like mad in a corner n hope she dont chase ur arse....
if you see a boomer, try settling things with him and offer him food
if you see a smoker... cut his tongue off (while screaming, this really helps, for me it does anyway)
if you see a hunter, act dead on the floor, he might spare your life
they are my personal tips for the great game i was told to buy off wally =D
P.S if there is a horde and its on Expert..... kiss ur arse goodbye cos ur fubar....
