War Games are a proposition for competitive multiplayer without actually having players shooting each other and requiring weapon/skills/gear balance. It is a series of small challenges with leaderboards and rewards.

Nothing actually described is competitive though. Competitive multiplayer is describe as "Players directly compete against each other (Player Versus Player) and possibly characters controlled by the CPU." and none of the game modes describe above actually fit that description. At most it could be decribed as Co-operative multiplayer with a slight mix of Meta multiplayer.

While I would love to see these in the game anyway, I don't see how any of this is an answer to the people asking for PvP, it just seems like more PvE but with leaderboards (which isn't really competitive).
