That (to me) just looks kind of boring running around with an SP shooting specters & grunts. If I were to get bored enough to play TF like that then it'd be time to retire Titanfall. IJS.
That's how I feel. Killing minions with no one else on your team shouldn't be a world record. I'd rather see someone at or around 200 with a whole team that is actually trying.
I just want to point out something. I know some may not respect a game like that and killing a lot of minions, but there is something that is extremely impressive about it. I've been in many games where it was 2v2 or even 3v3, where time ran out before either team could even reach 300 points. For 1 person in a 1v1 game to get 300 points or close to it is amazing to be able to do it before the time runs out.
