First I should clarify that this only works on bots, not human players. Still, it's pretty useful, both for map designers and mod developers.

This mutator displays some extra data on the screen on whatever bot you're looking at, including navigation path, enemy, and various technical things. You can also watch a flag instead of a player.

He's guarding that flag pretty intently. Notice the green box marking his Order Object.	Course plotted and laid in.
There's an AlternatePath at the end of this path.	Some of the states are pretty descriptive.
How a bot snipes. Note the red crosshairs marking the bot's enemy.	Another descriptive state.
Always know exactly who has what flag where.	Or follow the flag just like you follow other players.
