Mine is somewhere around 155 I think. Just barely got my 3 stars. It was against legit competition with legit team mates. 5 on 5.
My highest has been 164 on Overlook. I find it impossible to get three stars in Attrition, unless you are running with a team of noobs, it's really difficult to get that many points before the game ends. At least that has been my experience, I'm also not a grunt farmer. I've been tempted to run with a SP just to attempt mass grunt killings for those 3 stars. However, I like killing pilots too much.
I had 248 one time. It almost has to be the perfect situation. It was on Swampland and I was my by myself against 2 complete noobs. I didn't use a burn card, but once I got in my Stryder I never lost it and was just mowing down minion and pilots whenever I could find them. I've had at least 3 other games between 200 and 220.
You almost feel sorry for them... Naaah. (I kinda do actually) got slapped in this game already in progress with a losing score of 23-7... Boy did that escalate quickly...
That is extremely impressive. I think what might blow past most people here is how hard it would be to get 300 before the clock runs out on you. Sometimes, even in a 2 on 2 or 3 or 3 attrition game, it will say "Match Ends In 30 Seconds" and the game ends with the winning team having a score of less than 300. To be able to get 300 points by yourself in the allotted time limit is pretty freakin' amazing.
Got 222 Friday morning. I think there were some new players. I really didn't want to demolish any trial players this weekend. Me personally I'm all about the challenge but I do realize not everyone is like me and I want TF2 to get some sales outta this experience. Either way I did have a cpl monster games.
