Ahead of the Back 4 Blood beta, we got to go hands-on with the upcoming cooperative zombie killing shooter from developer Turtle Rock. In our time with the game, we only got hands-on with the PvE campaign. But afterwards, I sat down with Turtle Rock executive producer Lianne Papp to talk about all aspects of Back 4 Blood, including its PvP Swarm mode, which Papp describes as "snackable" (a term I will be stealing and using to describe many games from now on).

Swarm mode is a best-of-three-rounds competition, in which two teams of four go up against one another. One side plays as the human Cleaners who need to survive as long as possible, while the other is composed of the zombie-like Ridden that must kill all the Cleaners as quickly as possible.

Between each round, teams switch sides and the winner is whichever team manages to get the best score. According to Papp, there's no concrete time limit to the rounds. Theoretically, they could go on for a very long time. But the mode remains a snackable escape because rounds are designed to prevent the overall matches from going on too long.
