Halo: The Master Chief Collection hit Steam earlier this week on Tuesday, December 3rd. Despite this being only the fourth day since the release, the Collection has already sold over 1,000,000 copies. \n \nThis statistic comes to us from SteamDB, a third-party database that tracks numerous statistics on Valve's digital retail library. The database tracks the population of games, the general playtime that people spend on them, the number of copies sold, and a variety of other statistics. \n \nSpeaking of population, the Collection continues to pull in dozens of thousands of players. The all-time player peak came at launch with a little over 161,000 players. Recently, it peaked out around 93,000, and there's still around 53,000 playing as of writing this. \n \n \n \nIf you haven't been following the Collection, you may not know exactly how it works. The Collection includes seven games all in all: Halo: The Master Chief Collection, Halo: Reach, Halo: Combat Evolved, Halo 2, Halo 3, Halo 3: ODST, and Halo 4. These games aren't all being released at one time, and are instead being released between now and 2020 in chronological order of the story. \n \nHalo: Reach comes first in the story, serving as a prequel to the original game and showing the fall of the planet Reach. After Reach, the games will be released in the order listed above, culminating in the story of Halo 4 and the events therein. \n \nPurchasing the Collection is essentially a preorder for each game, allowing you to install them as they're released. Otherwise, you'll be buying each game individually, which ends up being a bit more expensive in the long run. \n \nCurrently, Reach has the Forge and Theater modes already included, with Campaign and Firefight coming in later DLC as a separate add-on. As the games release, there will eventually be a full campaign spanning 67 missions, as well as over 120 multiplayer maps. \n \nFinally, the Halo Insider Program is ready to engage with community members and find ways to improve the games, products, and services that 343 Industries provides. This program provides opportunities to join in on public flights of in-progress releases, as well as to provide feedback directly to the development team. \n \nIt's fantastic to finally see such a legendary franchise coming to PC. Gamers have been asking for this for well over a decade since the release of the original Halo, so it's wonderful to see it actually coming to fruition. Whether you're in it for the multiplayer or the campaigns, the Collection is bringing it all to bear.
