A very underrated Call of Duty Game which tried new things which was panned. But I believe looking back on it now it did amazing things. Fun unique multiplayer maps like Temple, or Cabin, or Alien Pit for dlc. A unique mode know as Extinction which differs from zombies being instead aliens with each Alien being unique. The guns all felt amazing to use and the amount of customization with you being allowed to play as iconic Call of Duty characters is amazing. While agreed the Campaign is very mediocre, the amount of love and dedication put into this games really deserves a second look by fans.
