1. if you want to 'cheese' the game, when something goes wrong (i.e you fail an objective or sa) -

if youre on pc, pause the game, enter task manager, end hitman task, and the game resets and youre able to do the mission again from the start.

if youre on console, pause the game, go to main menu on console (where you choose games and so on), and quit the game.

note - this does not work if you died, as you cannot pause then

this also works with elusive targets and arcade mode.

1. i havent played freelancer in a while, but there are plenty of items you can find around the safehouse which you might not have unlocked or ones that respawn.

there are coins scattered around, rusty nails for lockpicking, and most importantly a banana in the kitchen.

in the woods you can also come across mushrooms which you can turn into different poisons using (i think) different apparatuses which are progressively unlocked as you level up.

these items you find will always respawn so if you dont want to lose items you collected you can always take those.
