I have recently changed the infobox code to make it a bit more readable for people who aren't used to editing them. The main focus was to change numerical label fields into what the fields actually represent (i.e first --> game). I haven't removed the old labels to reduce the work of changing every page to the new labels.

I have also changed the map label to "map" (plus up to map2, map3, etc) but I have not removed the field that makes "image1" or "image2" into maps - this will need to be changed in the near future, requiring a lot of work. In the mean time, you can use a <gallery> tag like on the Torture Cells page, or use the {{Infobox2}} template like on Ever Black Shadow.

There is a new field on the Easter Egg infobox called "reference" that can be used to describe what the Easter egg is about, my example is on the True Grime Street Cleaners page.

If you have any other suggestions for new infobox fields, feel free to suggest them. And you can get acquainted with the new labels by checking the documentation on the infobox pages.
