No. That's not a fact. I'm an very old player of CubeCraft but lost my account 3 years ago. I've been playing Assassination 3 years ago, and there was sometimes a hacker with killaura. Not that bad, it wasn't that hard tho. Maybe 2 or 3 hackers on a day? Believe me, don't talk if you don't know. Join Assassination for a day, there are at least more than 5 hackers in 1 hour. Now they started to join FFA too, both games are almost not able to play. I never see your name in Assassination, so I don't understand why you give your opinion if you don't even know how it goes. We play Assassination everyday, we know everything. We've been through it.
Today i've been killed by a hacker this morning. Yes, at that moment there were 2 hackers. ---- > At THAT moment. Then I left for a while and joined back. I reported another hacker on #staff-help. Later again someone else. I've been afk today a lot. But everytime I join Assassination, there will always join a hacker. People don't report cheaters on Assassination at Forums anymore, sorry.
Sentinel is most of the time pretty late too. Most of the player have good clients so it takes sometimes longer than 20 minutes before they get banned. Enough time to kill the whole map, so that's false. Sentinel catches the people with bad clients in 5 minutes, sometimes 10.
Maybe you just joined Assassination, but at night there aren't that much players so no reason for a cheater to join. Theres almost every night a hacker but not always. In day, it's worse. Believe me. Don't talk if you don't know anything about it.
