I'm making a melee only map, where there are no objectives other than beat the crap out of everyone else. However, this map will be filled all sorts of fancy mechanisms, traps, and exploitable areas. However, I want to have the intel there as a sort of key: If you hold it, you can get to some areas others can't. However, I don't know how to make it so only people with the intel can walk through certain doors. Any help on this?
