Forum:Upgrading killstreaks

I was looking at another watercooler forum, and I got the idea of upgrading killstreaks. There should be 4 levels of the killstreak, and you start out with 1. Tell me what you think, and if you have any ideas (I don't) for this, then you can also post those.Goodboy12 16:08, July 2, 2011 (UTC)
