They need to type in 4 8 15 16 32 43 beside a >: prompt in the hatch. Did you guys notice that the prompt is a frowning emoticon (rotate 90 degrees counterclockwise)? so the numbers are cursed and hugo is right?

In this day and age, it is very easy to think of this as an evil emoticon because we have emoticons for everything. However, for that computer it would be completely normal as that is the command prompt for DOS.
