This is the sound clip from Valorant that plays with Reyna Ace. You can use this in Call of Duty: Warzone to change the sound when someone gets an ace (or anything really, depending on what you use this for).
To install, simply add the MP3 file in your Warzone sound folder! Enjoy.
If you actually want to be able to get an ace in Warzone, I'd recommend a stable, automatic weapon that lets you check off your kills easily and quickly. A CoD expert presented the 10 shooting irons with the lowest recoil and MeinMMO also provides you with setups and the damage comparison. Don't forget to track your Warzone stats to see how you're doing against other players.
Why are stable weapons so important? Pinpoint weapons that shred enemies like an experimental laser beam give you a serious advantage: you hit your target. But just because this sounds logical and trivial, don't underestimate this simple fact. Because a high hit rate in Call of Duty: Warzone is often proportional to the damage dealt. If you use a more stable weapon, it won't deal out as much damage as an untamed damage monster.
