Item description:

Duke Nukem 3D 200/200

Every save in each episode is right at the end of the level, just hit
the nuke button to complete the level. You must load and complete
each level in sequence.

The game saves your progress to your profile so as each level is completed,
the next is unlocked. Just playing the end of episode Boss levels won't get you
the achievement unless you've cleared the previous levels first.

Boss levels are saved just as the boss dies, so watch or skip the cutscene
and the episode achievement will unlock at the stats screen.

Misc
game0.sav - Press use button to tip the hooker.

game1.sav - Use Shrink Ray on all the eggs in
this room and then step on them.
Simply reload the save and repeat.
There are about 15 eggs, so it will
take about 2.5 reloads to pop the achievement.

game2.sav - Just step on the Turd in front of you.
