My son and I have been playing egg wars a bunch the last few weeks and have noticed many hackers. Most of the time they jump to islands and break eggs and then go away. We have started recording all games we play in and have already reported 2 obvious hackers. The mod team took care of them due to the reports.
I don't like playing with hackers, but many times we end up beating them if our color team works together. It's a great feeling when your team beats a hacker. Oh, and sometimes we may think someone is hacking , but there may be some lag and it seems they are hitting us from farther away than they actually are. Be careful to assume its always hacking.
Also be aware that on some egg wars maps you can exchange emeralds in for a knockback II axe which can send players flying off into the void. Do not accuse a player of hacking if they have that axe and you find yourself sailing into the void.
