*Hacker infested -- If you spend a lot of money on NX you will not get banned for using hacks in this game. You might get your stats rolled back, but even the top players can hack and get banned multiple times and still keep their accounts. It's sad.
*Badly optimized -- why do I get fps lag after some time playing this game? It's certainly not my OS, or my hardware. It's universal.
*Terrible community -- full of immature children. Expect to get kicked for killing the elite moderator or questioning whether he or his clan hacks.. Or a clan composed completely of secret hackers, and own the room as elite moderators.
People playing simply to grind GP/XP, what happened to playing for fun and slowly advancing towards your rank, so that it actually means something? I understand, but it's sickening how now you can get a high rank in a few days with what took people months before all the xp boosters and crap game modes came out. Ranks used to be respectable, now Nexon has taken away what people used to treasure about advancing ranks in the name of greed. That's inexcusable.
*Buggy -- How many times have I died from walking down a ladder and all of a sudden killing myself
somehow, what are the laws of physics in this game that dictate walking down stairs might kill you. Is it haunted? Did somebody murder a woman and her unborn child on those stairs? What's the story, Nexon?
*Unbalanced in almost every way possible -- Dual SMG's > everything on most maps. NX weapons give advantage in many cases. I know Gaben wouldn't let that ♥♥♥♥ roll, that's for sure.
I have played this game from 2009 ~ 2010, a bit in 2011 and 2012 as well. Right around the time when they released specialists (2009) is when things started to get bad. The game is engineered around NX now, no way around it. You can't play things like quarantine mode anymore unless you pay money for mutagens.
There is speed boosting armor in the game that adds up to +25% if you pay money for NX. As you can imagine, this is frustrating. Good luck trying to kill a skinny female character bunny hopping around with an SMG with what is basically a speedhack.. Jesus, this game is terrible.
If you want to test your frustration, this is the right game for you.
