SAS:Zombie Assualt 4

Basically you just got to play it smart. Don't use stuff like invulnerability, don't give yourself skill points. Use the wiki and learn what weapons drop at what level so you can give yourself believable weapon drops. I know for a fact that having more skill points than like 110-ish will get you flagged by the system itself. I've heard (but never tested it myself) that collecting more than 14 or so crates in a single mission will also flag you.

Using the trainer thing you can use the cost 0 hack with no penalty, the Wide Weapon/Armor range, and the +3/+10 hack all without fear of being flagged as a cheater. However using the Weapon/armor range you have to be careful not to use weapons that are far above your level, like a red Hiks at lvl20 will get you reported faster than you can complete Pods.

confirming that collecting more than 14 crates in any mission (SP or MP) is an auto MP ban.

Well in order to not get MP banned, make sure that you apply hacks according to your level. For instance, if you're level 35, then hack weapons only near that level, don't just start hack weapons way off your level, you'll just be reported and banned on multiplayer.

Also, don't use the grenades hack just for grenades, only for money, and reload after you're done. Don't hack your armor or damage in a games as a low level, people will find you suspicious and report you. Thirdly, never hack your skill points, that's an instant ban right there, so just use it on alt accounts. I have hacked my character and yet to be banned. All I've done is hack a few black gear MY level and equip them, the rest I just earn keys to open. Never do a mastery hack until you're level 95+, people will instantly know you're a hacker if your mastery is level 5 and you're like lvl 30. Also, I suggest that you don't hack your level because low MP games or kills will make people think that you're a hacker.

That's all the suggestions I've followed and haven't got banned yet. Try following these and you will never be banned.

Guys, I have an idea.

Is a hack that hides the skill points hacks make-able? I mean, it works like this:
You have everything maxed out to level 25, but others do not see it that way, they see a fair skill tree. Wouldn't that solve the problem? I am not sure if a hack like this is possible or not. Either way, I think it's a good idea to try and make one.

That wouldn't work, because other game clients are not pulling Your information from Your computer.  They are getting it from the game server.  If you're stats are 10000 on the SAS servers, then anyone looking will see them as 10000.

hm yes, if you ARE going to hack, i find it that hacking at low lvls is just far too risky - too many factors that compromise your legitimacy as a low lvl.. skills, weapons and armor, mastery, pretty much everything is there for others to see in mp. and at high lvls you are risking hours of gameplay going down the drain... its a risky deal!
