I believe that it's when the level cap was 30, and when only a few people had the anti-material sniper

But the video is is 1 and a half year old, so things would change between there and now (such as Ghostbusters pants, Cyber Ninja Head and stun grenades which is a good sniper set). I can reach up to 30 kills with that set + anti-material sniper, but I played the game later than Chase and I used armor with perks.
