E1M2: Castle of the Damned
From the Nailgun to the Rocket launcher and further to the Yellow armor
by Jjonez

Starting of next to a lowly Nailgun, a plunge in the water and a brief swim leads to the mighty Rocket launcher. Some more swimming and an elevator goes up into the central bridge area where the Super shotgun is available. Taking a winding walkway over the water and braving a nail trap, the Yellow armor comes in view.
On to the second tour.
