Duke Nukem 3D Hints
Where's the blue key card?
1 of 11: The blue card opens a hidden door by the road on top of the bridge.
2 of 11: This card is rather hard to find, but with a bit of ingenuity, you can get it.
3 of 11: Look up at the buildings.
4 of 11: There should be two windows open.
5 of 11: One of them you can't open until later.
6 of 11: The other one is close to the tipped-over building.
7 of 11: Jump on the demolished building, and then hop into the open window.
8 of 11: This can be difficult, so keep trying.
9 of 11: Another tactic is to fall into the hole in the demolished building.
10 of 11: Inside is a jetpack that can not only get you back out, but also offers an easy way to the ledge.
11 of 11: Anyway, you'll find the blue card on the floor in that area.
