It's no secret that a lot of people are playing the new free-to-play Call of Duty: Warzone battle royale. As reported yesterday, there are already 15 million players, and Warzone has a fun battle royale twist, with "camps" where players fight to the death in 1vs1 matches for a chance at a rematch. While waiting for their chance to fight in the camps, players can stand on the balcony of the match venue and watch the current duel. From this balcony, they can throw stones at their combatants, inflicting a pathetic 1 point of "non-lethal" damage. But players have already found ways to kill with rocks, through both obvious bugs and ingenuity. Here's what rocks usually do.

Gulag's equipment in a 1vs1 is random and can include almost any weapon in the game, including claymore mines. This is an example posted on Reddit, where the operator is caught in his own trap. Apparently one point of non-lethal rock damage is enough to activate the mine.

There are also reports that the rocks are not actually non-lethal. In a video of what appears to be this bug, a player is killed by a rock, and there is also confirmation of a kill by the player who threw the rock
