The achievement list for Halo: The Master Chief Collection has been revealed and it's... impressive, to say the least. The four-game bundle comes with 400 achievements totaling 4,000 achievement points. These numbers alone are probably enough to make any Halo fan excited, and make achievement hunters crack their knuckles in anticipation.

But Master Chief Collection's achievement list has more going for it than just its massive size. 343 has done a fantastic job designing this huge set of challenges. This might just be the best collection of Achievements in Xbox Live history.The Halo games have always been rock-solid and bug-free... mostly. A few notorious (and often hilarious) bugs gave worked their way into Halo 1-4 over the years, and Master Chief Collection's achievements now make them official. Riding the Pelican in 343 Guilty Spark and acquiring the Scarab Gun in Halo 2 might only mean something to hardcore Halo players right now, but a new generation is about to discover these old glitches thanks to Master Chief Collection's guiding achievements.The best achievements in any game actually add replay value by encouraging players to replay game segments in crazy, unintended ways for fun and glory. Master Chief Collection has several, including Feet Firmly Planted (beat a Halo 1 level without jumping), Begins with a Single Step (complete Tsavo Highway without entering a vehicle), and This is My Rifle, This is My Gun (complete Halo 4's Infinity using only UNSC weapons). Even Halo fans that have done it all will have something new to attempt.Master Chief Collection brings back campaign scoring for all four Halo campaigns, and devotes 90(!!) achievements to beating par scores and par times, ensuring anyone even remotely interested in the achievement list will become intimately familiar with the revised campaign leaderboard system. It's another system that smartly adds replay value. Playing for speed is very different than playing for score or hunting for easter eggs. Levels that are easy to clear on Legendary might be tough to speed run, requiring players to be adaptable and innovative, and know their Halo inside and out.What's absent from Master Chief Collection's achievement list is almost as important as what's included. Most notably, there isn't a single poorly-designed multiplayer achievement in sight. No need to get a double kill with the Spartan Laser. No need to destroy a warthog full of opponents. No need to score an Overkill. All of MCC's multiplayer achievements revolve around simply winning games, and earning medals. Winning 500 games, and earning 10,000 medals might be a grind, but it'll all happen naturally just through normal play - no achievement boosting necessary.Playing the Halo games on Legendary is no joke. Playing them with all of the game-changing skulls on can be maddeningly difficult. Several achievements in The Master Chief Collection require you to play the campaign in LASO -- Legendary, All Skulls On. Some skulls remove your HUD or take away your other reticle. Others make enemies much more inclined to toss out grenades like nobody's business. This is going to take patience and teamwork in spades, so don't expect to max out this game without putting up a fight.We're covering Halo: The Master Chief Collection all month long for IGN First.
