Save This Film

Save This Film is a Halo 3 achievement which was awarded for earning a Perfection medal on one of the Mythic maps in either a ranked or a social playlist.

To get a perfection players needed to score at least fifteen kills with no deaths in a Slayer match. Note that it was not necessary to get the Running Riot medal to get this achievement. If someone quit the game, it would sometimes cause the players' sprees to reset, but as long as a player finished the game fifteen or more kills and no deaths, the medal and achievement would be awarded.

This achievement is worth 25 Gamerscore and is represented by the outline of a by the Perfection medal.

Following the shutdown of Xbox 360 Halo online services on January 13, 2022, this achievement is no longer attainable.

Tips
One method was to try to stay back and let your teammates do the work, and occasionally pop out to finish off someone else's kill. On Sandbox players could hide behind the structures and obstacles and eventually this achievement should unlock. To make it easier to survive, it was a good idea to: have a bubble shield or a regenerator on Sandbox; utilize the rockets for quick and easy kills as much as possible; watch out for the enemy warthog and players wielding rockets; always be patient and not be rash in order to better survive. Once players got to fifteen kills, players could consider hiding behind their base and waiting for the game to end.

It was also possible to get a teammate to drive the player around in a Warthog circling the map, being careful not to stray too far out, otherwise the Guardians would kill them, and not too far in as there was a greater risk of getting stuck by a plasma grenade or blown up with a rocket launcher.
