Nuke is right. There are cheats and hacks that works like a charm for Infiltration, including aimbots (and no, I won't tell you what they are called). And yes, there have been proven and even admitted cases of cheating and I'm sure we haven't seen the last of them. That was the main reason why I took the initiative to establish the first private forum for server admins several years ago. The forums have died and risen again more than once since then and the forum is still alive, even though they have their slow periodes.
Things improved with the release of 2.9, but no matter what you do, there will always be leet kiddies who will try to cheat, some will even succeed, mostly because they think it makes them look cool. And because it gives them an excuse to yell "OMGWTFHEADS0000TLOLOLOLZ!!!11".
I have yet to experience a cheat free online game. Infiltration is no exception. Aimbots and other hacks will always an issue as long as they can give people an advantage, no matter how stupid, pointless or irrelevant the advantage may be.
