Treyarch have compiled a brand new Call of Duty 4: Black Ops 4 trailer to celebrate the launch of Infected mode.

Infected is now live on PS4 and it comes with a rather simple concept. One of your party members will turn into a zombie right at the beginning of the match. After that, he needs to spread the infection and basically...kill everyone else which will cause them to win the match. In the meantime, non-infected players better run away from them. Well, at least until the timer runs out.

The mode will hit PC and Xbox One at a later point in time. In the meantime, enjoy the PS4 version and this amazing trailer:
