I like how the game rewarded me for dying for the first time and it saves as well so i dont see dying as a failure, i see it as a small pebble while climbing a mountain!
the first time i played i found out i could switch to easy mode.
and when i did immediately after, someone told me i should be ashamed on easy mode. i switched to normal right after she was done talking.
if you blew up a platform that can get you to treasure try the zombie jump: (WARNING: if you have low health and\or no health packs, don't do this!) find a nearby zombie and get him near the ledge. jump on him and jump off him onto the ledge! note that you WILL get damaged a bit or a lot depending on how fast you jump on and off him.
do his henchmen ever bother to close the door? did it fall off or do they just like keeping a door ajar even though their spoils are falling out of it?
just like real life !
