FFor me halo 4s multiplayer was incredibly underwhelming, the story just wasnt needed at all never felt like a sequel to halo 3, ganeplay wise like someone said it was casual, obviously going for the cod fanbase at the time, multiplayer was pretty poor especially compared to reach and halo 3, halo 5 was just awful especially since the beta at the time felt incredible, you felt like you were in a spartan armour but when the final product came out they removed it, the new characters in halo 5 were shit to put it nicely and also feel out of place, making buck from an odst to a spartan was just odd, no thought to it and was clearly there for fan service, i will gove credit to halo 5 that its multiplayer was alot better then halo 4 but again it just didnt have that bungie feel and magic, one of the biggest problems i have with both games is the art style as well, it just doesnt work and the prometheus also feel out of the place, like the sentinels in halo 1-3 are meant to be Promethean technology yet they look nothing like the other promethean enemys, even if halo 4 and 5 werent halo ganes there incredibly medicore at best and wouldnt have the same amount of sales if it was for the halo name, im hoping infinte is the start of something good from 343 as 4 and 5 are incredibly week games and i hope the rumours of infinte taken the timeline from 4 and 5 are true
