This game is garbage and anyone who has purchased it should get the next game for free (Late 2021).
Let me elaborate.
The multiplayer is very fast paced. So much so that it is quite unenjoyable. The time to kill is way too fast, which means that when someone is shooting you or when you're shooting someone else the characters die extremely fast. This stops people from going on streaks.
Even the maps are not so good. There are too many places where people can head glitch, and the head glitch is very advantagous. This means that when your opponents are behind something you can see the smallest part of their head and it is very hard to kill them. However, from their perspective that same opponent has a clear view of you and can kill you very easily (Especially because the time to kill is very fast).
It is very hard to see characters at a distance in the game and because you can die so fast sometimes you don't even see where you get hit from until you watch the kill camera (Replay)
The game has been designed to try and keep everyone at an even playing field, and by doing so the game has lost it's savour. The game has great potential but that potential is over-shadowed by the excessive need to make money off of players.
It is easier to have more players if the game is an even playing field and stops the more skilled players from doing as well as they would normally do. The game no longer requires much skill. Simply just hide behind a box and you will get more kills then if you tried to maneuver any of their very poorly designed maps.
This is all factual and can be backed up by the evidence of content creators. Many content creators have stoped making content for the game because it is impossible to do well and also because the game is not fun.
I have been an avid Call Of Duty fan and I've purchase almost every single one that has come out.
If I had to advise you, I would say do not purchase this game. It is very bad.
I'm just praying that the next one is much better and can return COD to it's former glory.
