Tighten Up The Graphics

 is an achievement in Halo: The Master Chief Collection. This achievement is obtained when a player completes every level of Halo 2: Anniversary having seen it in both classic and remastered mode.

Trivia
The achievement name is a reference to Westwood College commercial from 2005 where 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 became an Internet meme.
