It is possible that a key is destroyed or lost during a round (e.g. by dropping it into the abyss or a deathtrap). The key carrier who lost or destroyed the key will lose the round for the team. The color of the key does not matter. This can happen for one of two reasons:
1. The key carrier destroyed/lost the key due to own clumsiness: The team is “punished” by rewarding all other teams with a few points. This will appear as “destroyed” in the scoreboard
-2. An opponent pushed the key carrier violently into the abyss or a deadly liquid which destroyed the key. This awards the attacking team some points. This will be counted as a “push” in the scoreboard
+2. An opponent pushed the key carrier violently into the abyss or a deadly liquid which destroyed the key. This awards the attacking team some points. This will be counted under “pushes” in the scoreboard
Finally, you can drop your keys by pressing the “Drop flag/key” control. It's [F] by default.
