I gave it a 9/10.
Pros:
+Great gameplay, gunplay and movement
+Best graphics ever in a Halo game
+Solid map design
Cons:
-Not a fan of FTP game design.
-Feature creep GAAS game design leaves us with less features at launch, but probably more in the end. This will probably end up being a positive, as it will keep the player base engaged and always wanting more. It just hurts a little at launch, because there are less features than what long time Halo fans normally have at launch. Just adding a Slayer variant playlist and Objective variant playlist and maybe a few more game types like Lone Wolf, Team Sniper/Shotgun, SWAT and King of The Hill would make a world of difference.
-It would be nice if the Challenges were more like those in MCC and rewarded good gameplay and not lame weapon based Challenges or rare one off task Challenges, that has people doing lame shit like hunting around for a specific weapon or looking for a vehicle to grapple, etc. Get 10 head shots, earn 10 Objective based medals, get 5 killing sprees, etc., Challenges are much better.
-This is a fourth, but cut the prices down in the shop and offer a 10% discount for Game Pass subscribers. Sea of Thieves offers a discount to Game Pass subscribers and it's great.
