Writing entries for the second version of the Encyclopedia is approaching the final stage. Version 2 will featured complete coverage of the No Exit novel and detailed information for the equipment used in Aliens provided by the Technical Manual. After that, proofreading will commence, so expect to see Version 2 soon!.
EDIT: Oh yeah, forgot spilling some hard facts: At present, the encyclopedia has 69 pages, sporting 13 pages of new content. However, as I write the final entries, the number will probably increase by 1-3 pages. In any case, I plan to hit the 70-page mark with this one.
