Well...
I wasn't scared of the bag but my sister was when she was watching me play...
The first time I saw one of these things I almost shit myself and died a lot... SO! I went to the merchant and got a rocket.. And incase you dont know how to kill them you either.... Find the special scope in the freezer... Blow off its head and an arm and take out its chest then take out a leg and throw a incenerary nade on him... Or just blow his ass to hell with a rocket...
