Fortnight doesn't have building any more. Fucking graat. You can sprint now, like actively sprint, which you couldn't do before. And two, you can mantle up to things, so you canlike, jump and then climb up a ledge,. Which is pretty cool. They it should be noted, building will be back, because it is so core two fortnight. But the response has been so positive for them removing building that i would not be surprised if it just became a permanent side mode that people could do whenever they wanted.
