Alright, today TF2 has been updated, you might have thought "oh another fixing update" but wait, in that update, Valve fixed the Kill icons for the community weapons, but now look at this picture (This has been taken here,this french website is a non-official one but they are serious and they explain the updates and changes provided to the game each time it's been updated). After watching it carefully you can see there are 2 myterious kill icons: That sentry seems to be a kind of laser sentry (you can see the 3 normal kill icons for the current sentries, so that's obliged that's a new sentry), and a black headshot kill icon, but we can't guess a lot about it (maybe a special laser sniper? ). I wanted to share this with you guys, mystery mystery...
