Speedhack.
At the beginning of the round, he reached the point B very quickly.
Video shows that while we are running from base to point B, they are flashing D,C & met us on B.
There were two of them on B (NeySevour & SCORPION_095), but he was the first in front of all and managed to kill the enemy. Second by the number of scores, we can use the exception method to understand who use speedhack, and who just spawn on him.
SCORPION_095 have 10 scores after i kill him. Respawning player on you give you 25 scores. Hi spawn on NeySevour, take point B 1 second (which gave him 10) & die...

Thus the SCORPION_095 falls out of suspicion and remains only NeySevour.
Other players:
WhyAitch    - 660 scores
Jamel_Lba5a5 - 520 scores
LordObunga - 70 scores

I not suspicion him. Teking point give you 400 scores & WhyAitch with Jamel_Lba5a5 teke points E & C.
LordObunga was closer to point C with WhyAitch. To this place it is quite possible to reach this time without cheats, considering that we lingered on a shootout
