Put it at the very start of a match montage, before any action clips, then follow it with Okay Let's Go as your team moves out and Enemy Spotted when the first fight begins, so the sequence builds from kickoff to combat.
About this sound
This is a short 1.8-second voice clip from Halo Reach in which a voice calls out 'play ball' in a clear, energetic tone. It feels upbeat and competitive, like the moment just before a match begins, and it gives a quick burst of excitement to anyone who recognises the game's multiplayer voice.
