As the title says, a friend and I have been playing multiplayer coop missions a lot recently. It's all fine and so on, except stamina is really making this specific type of mission tedious. We want to extend the duration of stamina from say 10 seconds of running to 20 seconds. I know it's not as simple as that, but hopefully that will help you better understand what I mean. I've seen this done before by users such as R34P3R who has made numerous coop missions where stamina has not been removed but instead extended.
Thanks to all!
