The gameplay wasn't very fun, there are often so many enimies that it just gets frustraiting you can't just sneak past them lile other games because it arbitrarily stops you from going ahead, ammo always runs low and runs out way quickeer than other games, and for some reason they gave this game Reach power ups and running which running barely works as there is a limeted sprint but there isn't a indication on how much sprint you can use so it seems to jist run out randomly, and items don't really do much gameplay wise(except for one jet pack level) and just don't make sense to me from a logical standpoint for why there in this game.
Most pf the levels in the middle of the game feel the exact same sharing the same basic structure, where you take down three or so generators to take down the big weapon and it gets old and very repetitive.
Story is fine Cortana and Chief's relationship is probably the better part, didn't care for the Didact or the angry captain of the Infinity.

Fun side story of Halo 3 but it did take me a bit to get used to the gameplay as it does change some things from traditional halo 3 as you are obviously no longer Master Chief or the Arbiter, and based on my initial impressions I'm a little confused about the Epilogue and how it actually fits with Halo 3, Buck's charactor and his romance with the captain was also annoying in my opinion and some of the dialogue from the playable characters was the worst part about the game in my opinion. Still like I said a good game worth your time if you like Halo.

Overall the overarching story peaks in Act 1 and fails to live up for the rest. The Challenge Mission get progressly worse and honestly I gave up getting the Ultimate score due to there literally ebing no reason or motivation to, same with any Bonus Objectives in the Enemy bases.

EP-1: The Heist - 9/10 A fantastic(and weirdly horny) continuation of the events of the main game, I was really engadged in this story and the side missions were really cool.
EP-2: TURF WAR - 6/10 The Heist would have been hard to fallow up on but damn, and Post game really started sucked here too with obscene challenges.
EP-3: SIPVER LININGS - 7/10 While still not living up to The Heist is an alight conclusion. The ending itslef kind stunk though, and after the credits roll the rest of the game was alright, although nither this or 'Turf War' will really stick with me in the same way Part 1 has.

I loved this game on Wii U, with it's cute and wonderful looking artstyle, and it's fantastic soundtrack!
I think for the most part it holds up but if you are looking to complete this game it is a SLOUG. Every level has 3 Diamonds you have to find, they basically just act as stars from 3D World pretty standard, but every level also has bonus challenge which you need to do in order to get a stamp on the level and a badge on the Episode on the menu and this task doesn't show up until you beat the level for the first time for some reason? it just seems like a given to make this appear when the level is available so you could at least try to get the challenge done in one go and it's annoying to have to redo the level because you barely missed a challenge you didn't even know was a requirement, as well as many of these challenges towards the end of Episode 3 are just absurd 'find the gold mushroom challenges' where it is invisible and in some random hard to reach spot and in Bonus Episode they are all just 'get X amount of coins' where you'll end up redoing the level multiple times because once you got 158 coins instead 160 and it's just irritating! Then you have to find Pixel Toad who in the Wii U version was locked behind the Amiibo which was weird but it just a cute bonus mode unnecessary for the game but now because it's not locked behind Amiibo it really does count and I'm really not a fan of them just hiding toad in random spots and having a slight audio cue to try and find him it's just irritating and he is hidden in EVERY LEVEL.
I don't know I think it's a cute game it's painfully monotonous and slow and in my opinion losses it's charm about half way through.
I've also found controls docked are funky with + being the reset button for the Gyro aim not just the Gyro aim button and to pause I can only use - docked than handheld requires touch so theirs not much of an ideal way to play.
I'm not anticipating playing the DLC this game didn't need and why didn't the Bonus 3D world levels make it to Switch yet?
