Duke Nukem 3D: 20th Anniversary World Tour

You can unlock “Nukem All” and “Rage Engage” in the same area.

At the main menu, select Single Player > New Game > Lunar Apocalypse > Overlord and select your difficulty. When the level starts, activate the cheat menu. Turn ‘God Mode’ on, ‘No Clip’ off and select ‘Give All.’

Make you way through the tunnel and emerge from the water when it opens up. Directly on the opposite side of the tunnel you were in is a vent near the ceiling. This vent is only accessible if you have a jetpack or if you are using the ‘No Clip’ cheat. Shoot it out and enter the short tunnel. At the end you will see a large rotating gear (there will be an Octabrain floating around so you can kill it or not; it’s up to you). Before continuing, press or to equip the pipebombs and or to select steroids, but don’t use them yet. Walk forward and drop down the shaft into a circular green room lined with eggs with a giant door at one end.

As soon as you land, pause and save your game. Then walk towards the eggs so they start to hatch then press to take the steroids and throw a pipebomb at the eggs. One pipebomb should kill five or more enemies. Keep circling around the room throwing pipebombs until all the eggs are destroyed and both achievements unlock.

NOTE: There are two reasons why you saved your game before falling into this chamber. First, in case one of the achievements doesn’t unlock, you can keep trying. Just time your throws further apart so one pipebomb kills five or more enemies. Second, this is a great area to farm 1000 kills for “Invaders Must Die!” Clearing the chamber nets 20+ kills, so if you keep reloading this save, you’ll have 1000 kills in no time.
