Something similar happened to me yesterday except we past 259. I was Nu gundam with 1 stock left vs the other team (Akatsuki, 2 GNAD, X Gundam) which all had 1 stock. Akatsuki & X were chasing me while the 2 GNAD were spamming missiles while I stayed in I-Field the entire time. Managed to kill the other 3 leaving 1 GNAD alive, then proceeded to spec with ranged.
Needless to say, the other team was pissed off. One guy said "How can one person kill an entire team?". I simply responded, "I'm a newtype".
