A new streak for Call of Duty: Black Ops 7 called Gravemaker gives players the ability to one-shot kill enemies through walls, and it looks extremely powerful and annoying to be on the receiving end of.

The Black Ops 7 multiplayer beta begins October 2 and runs through October 8, during which people can try out a selection of the game's modes and maps, along with Zombies.
