Here is a CryTek keygen for both Crysis 1 and Crysis 2. Some keys might not work but most of them will, and alsmost none of them will work online, but if you are the lucky one that gets it congratulations :P haha
I created it it myself, I just finished this today.
Hope you guys enjoy it, have fun
Here is the virusscan it showed a Sus/Keygen-A on the SOPHOS virusscanner but that's just because the program has the word KeyGen in it... so, use it or not
