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
Players attempting to unlock the achievement should avoid playing Halo 3 and Halo: Reach multiplayer matches, as they are the only games in the Collection which do not award either of the medals required.
