At the time of this writing, there are approximately five days left until the 11th day of November. In past years, this date may not have held great significance, but if you’re like us, you may have had a figurative “X” on the calendar since June of this year.

In just five days’ time, experiences both familiar and new await. On its 10-year anniversary, Halo 2 will return to Xbox Live, and bring with it a broad package of games and content. A newly re-mastered Campaign as well as a suite of re-mastered multiplayer maps have been prepared in Halo 2: Anniversary. Halo: Combat Evolved will make its Xbox Live debut, and perhaps even provide an opportunity for some of you to play the game that started it all for the first time. Halo 3 and Halo 4 (along with all other titles) will make their Xbox One debut in full HD at 60fps. The Halo Channel will be your new home for entertainment and programming, including the first episode of Halo: Nightfall. In addition, new terminals, hundreds of achievements, and more await. Your journey is about to begin, and we hope you’re as excited as we are.

This week, we have a few new topics to cover, including skulls, LASO playlists, ranks, a new eSports league, and more. Let’s get to it.

Halo: The Master Chief Collection - Skulls & LASO Playlists

Over the past few months, we’ve discussed skulls and campaign playlists, but now seems like an appropriate time to dig into these, especially when you consider that this is the last chance to do so. To get the latest, I grabbed Max Szlagor, Senior Designer on The Master Chief Collection, who proceeded to give me so much information that I just had to write it down. These etchings have been transcribed below.

The Master Chief Collection includes 37 different skulls, including several unique additions to Halo 2: Anniversary. Skulls are modifiers that can change Campaign gameplay in a variety of ways, and are closely tied to the Campaign scoring and timing systems, as well as leaderboards. With the exception of the pre-order skulls (which will unlock globally on December 12, noted with an *) and Swarm, every skull is unlocked and available from the start. Skulls are broken down into two categories: Scoring and Non-Scoring. Scoring skulls amp up the challenge and reward players with higher score multipliers or bonuses to base enemy values when turned on. Non-Scoring skulls can either be neutral, such as Grunt Birthday Party, or in cases of cheat-like skulls, have a score multiplier of zero. Zero multiplier skulls like Scarab disqualify level times and scores from being recorded on the leaderboard and disable achievements.

Here is a full run down of the entire skull list along with the games each skull appears in:
