Glad my whinging at the beginning was not benign, let's list the problems,
General;
Campaign End Cutscene Freezes Console. ...
Vanguard crashing on Xbox Series X. ...
Your CPU Does Not Meet Requirements bug in Call of Duty Vanguard.
Error Code VIVACIOUS. ...
Main Menu Lagging
MULTIPLAYER
-Aim assist is alot higher
-The graphics are actually backwards they somehow made it worse on the same engine
- The sound does not work at all BY FAR THE WORST PART
-The destruction environment now means no cover in the maps
-sbmm means no casual play - You play one good game your now sweaty lobbies
-ttk way too high and with the crazy aim assist you just don't win fights
-zombies is plagued with its own issues
-Visually cant see enemy they’re immersed in a textureless blur that blends into the background. Your generally shooting at floating name tags most of the time.
-enemy teams are same character models can not determine team or enemy entity
-slide glitching
-visual recoil shakes the screen
-weapon perks X10 makes no sense and plauged with errors....
-spawns are broken
-map designs
-general interaction and menu problems
-dev errors and crashes
-Visibility is very bad and the sun is extremely blinding.
Campaign
-balck screen errors for campaign
-Characters don't really feel distinct enough and campaign missions fail to distinguish them
-Emphasis on unique characters doesn't mix well with Call of Duty formula
-Some campaign missions are much weaker than others, especially when pushing out of the usual pop-and-shoot approach
Zombies:
Zombies is an insult to the people who paid $80 for this game, the game mode is Essentially one central hub where are you teleport to a few different areas which are very small portions of MP maps or old world at war zombies maps. They removed multiple key features like over half of the field upgrades are gone, majority of the perks from the previous game are gone, there is no existing pack a punch camo which is laughable, There is no main Easter egg quest, and the skills trees are gone so no more upgrading things in zombies. You can experience all that zombies has to offer in about one hour and then there is no reason to replay it again.
hope this helps in deciding whether to buy Vanguard or not. It’s essentially MW reskinned with worse overall playability.
