- The medal is a reference to Halo: First Strike and the common term "First Blood" in other games.
- A bug in the multiplayer beta causes this medal to reset upon leaving a host migration; the first player to score a kill thereafter earns the medal.
- The achievement "Yes, Sensei" is unlocked upon earning this medal in matchmaking. Once the achievement is gained, you unlock armor from Halo Waypoint.
- Although the description of the medal is getting the first kill of a game, it will actually be received for getting the first kill of a round. It is therefore possible to get the medal multiple times in games with more than one round.
