Does it really matter? I get a lot of grief for it like being called "Hey Resetscore, how you doing?" I just reply with a kind "It's my score not yours so you don't need to worry about it". As D_Day said you can do /resetscore so it does not show up in chat or type it in in console.
As long as i can shoot, enjoy with the others playing. And a slow-but-steady gameplay and the surprises made at the end of the day when i ended the game by checking the hlx stats, how much i gain, how much i lost, Plan the next round of gaming , the tactics, and much more. Now that i typed so much, i'm gonna get some drink. Too thirsty. X)
