Catch This
From Halopedia, the Halo wiki
Catch This
Catch This is an achievement in Halo: The Master Chief Collection. It is unlocked by earning a total of 500 Grenade Kill or Plasma Kill medals in multiplayer matchmaking. Strangely, Grenade Stick kills do not count towards the achievement. The achievement is worth 10 Gamerscore.
Tips[edit]
Players attempting to unlock the achievement should avoid playing Halo: Reach multiplayer matches, as it is the only game in the Collection which do not award either of the medals required.
Trivia[edit]
From launch until the April 2022 update, players could also not progress this achievement by playing Halo 3 multiplayer matches, as it also did not award the required medals. Following the update, assists can now be earned in that game as well.
