enemies cant drop anything but weapons. If you dont want a winzone don't place one. To make enemies the objectyive right click on every enemy one at a time and set the "isobjective" property to 1 then 2 then 3 and so the enemies become a list of objectives you can do the same to an item so picking it up is an objective. Don't give any two entitys the same number because i think that means you can do one of the other. Go to the fpsc chat board at the top you will see nikkydudes guide download it and read it all it will help you alot.
Thanks
