I don't know about you, but for me this has been one fun adventure, going from knowing nothing besides the names and icons to where we are now. Between the great effort of everyone, not just in NA but across other servers, we've managed to put together requirements for every one of the ten event achievements in just about a day and a half, summarized in the table below.
Achievement Requirement Possible Alternative Reward
King of the Party Get the other 9 event achievements Possibly bugged and shows up earlier for some players for unknown reasons 5000 Free XP
Life and Soul of the Party Get an in-battle compliment (compliments awarded from the post-battle screen don't count) - 25x Juliet Charle flags
Festive Soup Get 10 ship torpedo hits over any number of battles Get 10 torpedo hits from any class, carriers included 25x Juliet Whiskey Unaone flags
Fire Show Score 100 main battery hits over any number of battles - 25x India X-ray flags
Run! Admiral! Run! Playing as a carrier, score 4 torpedo hits over any number of battles Works on 5 hits for some. Bombs also seem to count. 25x Victor Lima flags
Queue Jumper Enter your first battle post-0.5.11 update - 10x Type 5 camouflage
Rise of the Machines In Co-Op battles, sink 5 bots over any number of battles - 25x Zulu flags
Big Roll Earn 1 million credits over any number of battles - 1 million credits
A Shot in the Dark Shoot down 15 airplanes over any number of battles Hit an unspotted enemy 25x November Echo Setteseven flags
Manners Maketh Man Complete 10 consecutive battles without inflicting any team damage - 25x Zulu Hotel flags
Special thanks to GG_Bootcamp for putting together a guide to achieving all 10 in a quick manner. You can find the guide here.
It's worth noting that while we have reliable requirements that are guaranteed to win you the achievement, there's some evidence that some achievements have at least two ways to get them, and achieving either requirement nets you the award. There's also still a big mystery surrounding how to get King of the Party without needing to get the other 9 first, but be assured that it is possible to get it by grabbing the others even if we don't fully understand how to get it otherwise.
I'll keep updating this post if new information for requirements comes to light (especially that pesky King!), but at the very least we now have a reliable way to get all 10, and hopefully turn them gold before the birthday celebrations kick off next weekend to see what these "special prizes" are.
The original post starts below
As you might have found out, the patch brought special achievements to celebrate WoWS' birthday.
But the trick is that WG won't say what triggers them, and we have to discover for ourselves. Each one awards in-game items, and making the achievements turn gold will apparently award special prizes. This thread is meant to compile what we know about the achievements and see if we can figure out all of them. You can track how many have been awarded server-wide from the main page.
