IMC has released a standard Christmas event for all editions of Granado Espada. See Rescue Rudolph! for the early information released for Korea/Japan Christmas event details. This blog post will be updated later as more information is released.
[Sword2] Christmas In U.S.
See Sword 2 Holiday Patch for Sword 2's official notice on Rescue Rudolph! event. Christmas Coins needed: 50 for Pet Box, 10 for costumes, and 5 for other items.
I don't know why the rewards cost so many coins though. The similar rewards in most other GE (e.g. Korea, Singapore, Taiwan) require 2/3/15 coins, while those in Sword 2 require 5/10/50 coins... I hope this isn't another screw-up like when they asked the players to type the horrendously long 8th verse from 12 Days of Christmas within 15 seconds last year. See also Christmas Carols forum contest.
Update: After being late for Christmas, the patch was amended to require 2/3/15 coins instead. Thank goodness.
[GE-SG] Christmas In Singapore
GE Singapore is having Rescue Rudolph! event - see Santa Needs A Favor!. Christmas Coins needed: 15 for Pet Box, 3 for costumes, and 2 for other items. According to Lorenza here, this event will end on Jan 20, 2011.
Cash cow milking continues with the final run of Adelina's Booty Search web game, featuring Elite Le Noir (DR 32) as top loot. See [ABS] Adelina's Retiring for official notice and forum discussion for how players failed to get any prized booty after 1,000 searches*. Meanwhile, Hellena's Circus of Fate web game continues to feature new costumes including the Santa costumes for Emilia, Grace, Adelina, and Calyce. See [HCOF] Winter Promotion.
Note (*): You can convert cash shop credit (G-Points) to ABS at the rate of 100:1. Thereafter, 1,000 ABS is worth 100,000 G-Points. SGD 60.00 (USD 45.65) provides 84,000 G-Points using iCash Card. So 1,000 ABS will cost about SGD 71.43 (USD 54.35).
