Cavalier

Cavalier is a Halo 3 Meta-Game Achievement. It is earned when the player earns 15,000 points while playing the meta-game on Tsavo Highway. This Achievement is worth 10 Gamerpoints to the player. A cavalier is a mounted soldier, and most of the level takes place in vehicles, which the player "mounts".

A blue circle with a winged sword, also known as the Valkyrie emblem, represents this achievement.

Methods
Turn on the Thunderstorm, Famine and Fog skull. These are probably the three easiest skulls. Warning:  whatever you do, do not turn on the Catch skull because on Tsavo Highway, there are many Grunts along the road and they will be randomly throwing grenades at your vehicle. With Thunderstorm on, the effect will be worse as the newly-promoted Ultra Grunts will pull a lemming and kamikaze run at you. It is important that you have a Chopper with you as well, as it is probably the hardiest solo vehicle. The other choice would be the Warthog, but after a while the Marines die and you won't have a person to man the turret. Also, turning on Tough Luck would cause even Grunts to dodge your vehicle when you attempt a splatter. This should most likely be played on Heroic or Normal depending on your level of skill.

Trivia

 * Cavaliers were noble horse riders in the Middle ages. The award is called "Cavalier" because most of it is vehicular combat.
