[botmeister]

The WhatsNew.txt documentation talks about the ban shield command. It does not work well for bots, but should work fine for human players.

The description link provided by KWo is correct, but mEAn tries to get around the problem by removing the weapon entity from the game, so the bots will still try and buy the weapon, but it won't appear in the game. This will mess the bots up a bit, but it does work. The shield however does not work in the same way as the other weapons and as a result it tends to create lots of problems with the bots.
