Tighten Up The Graphics

Tighten Up The Graphics is an achievement in Halo: The Master Chief Collection. It is unlocked by completing every level of Halo 2: Anniversary having seen it in both classic and remastered graphics modes. Viewing each graphics mode for even a second is enough to satisfy the achievement's requirements. The achievement is worth 10 gamerpoints and can be unlocked on any difficulty.

Trivia
The achievement name is a reference to a commercial for Westwood College Online from 2005 in which a video game tester says, "We just finished level 3, you need to tighten up the graphics a little bit" as feedback. As this is humorously nonsensical to anyone who has played or developed video games, it spawned an Internet meme.
