Halo 3:Asymmetrical and Symmetrical?

[Dragostea]

So when I was making some maps,I see these words on the item options and game-type options. I have no idea what these do to affect the game.Can someone tell me what the asymmetric/symetric options do?Plus,how can I use it in making maps and gametypes?Thanks

In short asymmetrical and symmetrical are used to refer to gametypes. Specifically this:

Symmetrical - Slayer (all), Oddball (all), KotH (all), Juggernaut (all), Land Grab/Flag Rally, CTF, Assault, Neutral Assault, Infection

Asymmetrical - One Flag, One Bomb, Territories, One-sided VIP

In your context it would refer to the map design being more suited towards an asymmetrical gametype or a symmetrical gametype.
