Unlock these 15 date-specific Xbox achievements over the holidays The holidays are here, and there are still achievements to unlock! Here are 15 date-specific Xbox achievements you'll need to pop over the festive period.Sean Carey Published 23 Dec 2023 FollowtopicsAchievement ReminderSean Carey You may think it's a time to relax and put achievement hunting to one side, but you, my dear friend, are wrong. Some fiendish developers have snuck Xbox achievements into their games that can only be unlocked over the holidays! To help you get a handle on what you need to unlock and when we've listed all the date-specific Xbox achievements that can be popped over the festive period. While some can be unlocked on December 24, most will require you to jump into a game from December 25 to January 1. For some of these, you can also just change the date on your console or PC to unlock them at any point throughout the year, but remember, Santa sees all, including your achievement unlock timestamps...The Swindle — December 24The first port of call on our tour of festive date-specific achievements is the You're a mean one achievement in The Swindle. This can only be unlocked on Christmas Eve (December 24) and requires you to clear a house in the slums of all of its loot, which isn't very festive at all. According to comments on the achievement's solution, this appears to be based on GMT time, so you may be able to pop it a bit earlier or later, depending on your time zone. The You’re a Mean One achievement in The Swindle worth 79 pointsClear out a poor person's house on Christmas EveHalo: The Master Chief Collection — December 25 and January 1Next up is Halo: The Master Chief Collection, where you can unlock three more date-specific achievements. The first you can pop is Elder Signs (provided you've already viewed one sigil), which requires you to view two unique sigils on Halo 3's Valhalla map on two different days of the year. This can be done in custom games, Forge, or in matchmaking, but only one sigil can be viewed at a time. You'll find the December 25 sigil —a Christmas light with a cross marked through it — located on a far wall behind a turret. For further details and more information on how this can be done offline, check out the Elder Signs achievement guide. Now, if you've viewed another sigil earlier in the year, you should unlock the achievement. If you haven't, don't worry. The next sigil will be viewable on January 1 (New Year's Day). The Elder Signs achievement in Halo: The Master Chief Collection worth 49 pointsHalo 3: View 2 different sigils on Valhalla.The Elder Signs achievement in Halo: The Master Chief Collection (CN) worth 21 pointsHalo 3: View 2 different sigils on Valhalla.The second Halo: MCC date-specific achievement you can unlock is the Destination Vacation achievement. For this one, you need to view one of the special seasonal signs on Halo 2's Zanzibar map in classic multiplayer on December 25. This sign can be found over on the beach next to the water, and it will read: "Danger, This Soffish, DO NOT EAT!" If you forget to view the sign on December 25, you will have another shot on January 1, where the sign will read: "Baby Shark Petting." For more details, check out the Destination Vacation guide.

All this one requires is that you fire up Halo 3 on the 25th day of any month, so if you're jumping onto Halo: MCC on Christmas Day, you may as well nab this achievement while you're there.The Third Time's A Charm achievement in Halo: The Master Chief Collection worth 9 pointsHalo 3: Play a game of Halo 3 on the 25th of any month.The Third Time's A Charm achievement in Halo: The Master Chief Collection (CN) worth 8 pointsHalo 3: Play a game of Halo 3 on the 25th of any month.Batman: Arkham City — December 25 and January 1We're off to see the Calendar Man in Batman: Arkham City next. To unlock the Storyteller achievement (or at least make some progress towards it), you will need to meet with Calendar Man on 12 specific dates throughout the year. You'll find the villain in a cell down in the Solomon Wayne Courthouse, which you can access almost from the beginning of the game. You can also visit Calendar Man on January 1 for another chance to unlock the achievement or make further progress. It's also worth noting that the achievement appears to go by the GMT time zone, so keep that in mind. The Storyteller achievement can all be unlocked offline — check out this Storyteller achievement guide for more information. There are also Xbox 360 and GFWL stacks available for Batman: Arkham City, so make sure you visit Calendar Man in those games, too. For the GFWL version, it looks like you will need to mess around with your system clock to get this one to work.

To unlock the Wasted Your Life achievement, you need to fire up the game and reach the main menu. Saw 2: Flesh & Blood has been delisted from the Microsoft Store, and it's not backwards compatible, so you will need to get the ol' Xbox 360 up and running for this one.
