TWILIGHT AT AREA 51 is one of the two major gameplay Expansions for Chronicle X. It adds three new miniatures (Grey Tall Men), and various cards, tokens, Map Tiles and a "Twilight Tracker" which is an extended game mechanic only present in this particular Expansion.
ERRATA FROM ARCHON FOR TWILIGHT AT AREA 51: Twilight Tracker, page 6: Change the first sentence to read: "At the beginning of the second round, set the Twilight Tracker to 1. At the beginning of each subsequent round, move the Tracker up 1 Space. After the Tracker reaches 6, you no longer move the Tracker and all of its effects apply for the rest of the game."
Expansion
There are a number of Expansions for Chronicle X. There are two major gameplay expansions:
- TWILIGHT AT AREA 51, adding three Alien Models of a new Alien Type Grey Tall Men, various cards and tokens, and 28 new Map Tiles.
- ABYSS, adding three Alien Models of two different types: one Ralavar Streamcaller and two Ralavar Waterbounds, various cards and tokens, 16 Underwater Map Tiles, and added rules for Underwater play.
Both of those Expansions also comes with an extended rulebook with some extra rules for features introduced in the campaign, plus a tiny Mission Book for Narrative Mode, useful as an introduction to the new game rules.
There was also a rather large Stretch Goals Box which provided a large number of additional Hero Models, many more Alien Models, and various other stuff.
Additionally, there is a [Solo/Co-Operative mode|Co-Operative Mode] Expansion, and a number of packs with additional Alien Types providing a wider range of choices for how to build the Alien Forces.
