Have a feeling that even if we get past the checksum, there is still the anti-cheat system to get past online and I'm also afraid that if we take our modded characters online, we will get banned.
Normally, I'm not worried about such things because I successfully took a few modded Borderlands characters online before without problems, but that was different. (Not much security/anti-cheat system on that one.)
With Shooters/First Person Shooters, people tend to notice these things more easily and report people.
The most basic solution is to not go online with those characters, but that'd be a little less fun.
I know before I said I don't condone of online cheating and that still holds true, but that's more in regards to things like "God Mode, Infinite Health, Infinite Ammo, Auto-aim" and etc.
All I really want to do is unlock every single ability for each class instead of being limited and that's it.
Think the anti-cheat system will cause any problems for us or get us banned?
