Hack/Decode game giveaway!

what was it?

Congratz :)

The PHP code would be known by programmers, web designers, and hackers:

eval(gzinflate(base64_decode('S03OyFd41DDDwzVCQV/BzETBVsEkRcHERMHEVMHcHMY2VDC3QLDNzJHUWGBTY4pFjSlEjTkhc5DVYzMH00ycapDEcboZqxpDFDdA1KDbZYjDHDT34HAbfrvwmWOIw++o4vjdTIwafG7G5R48aohxD9Y0Rowa1Dii3F/IdmFJYwT9hWwOnnSIYQ4+96C6zTjlUcNMawA=')));

Can either be runned from a web server or manually decoded by going backwards through it.
In this case it was Base 64 decoding. Then it was gzipped so extract from that.

If your really lazy about writing a few lines of code, you can use a website tool to decode such as:
http://ddecode.com/phpdecoder/

Either way you are left with:

echo ‘HEX / 64 = 4d 44 45 77 4d 44 41 78 4d 44 41 67 4d 44 45 78 4d 44 41 78 4d 44 45 67 4d 44 45 78 4d 54 41 77 4d 44 41 67 4d 44 45 78 4d 44 45 78 4d 54 45 67 4d 44 45 78 4d 44 45 78 4d 54 41 67 4d 44 45 78 4d 44 45 77 4d 44 45 67 4d 44 45 78 4d 44 41 77 4d 44 45 67 4d 44 41 78 4d 54 45 77 4d 54 41 67 4d 44 41 78 4d 44 41 77 4d 44 41 67 4d 44 45 77 4d 44 45 78 4d 44 45 67 4d 44 41 78 4d 54 45 77 4d 44 41 67 4d 44 45 77 4d 44 41 78 4d 54 41 67 4d 44 41 78 4d 54 41 77 4d 54 41 67 4d 44 41 78 4d 54 41 77 4d 54 41 67 4d 44 41 78 4d 44 45 78 4d 44 45 67 4d 44 45 77 4d 44 41 78 4d 54 45 67 4d 44 45 77 4d 44 41 77 4d 54 41 67 4d 44 41 78 4d 54 41 78 4d 44 41 67 4d 44 41 78 4d 54 41 78 4d 44 41 67 4d 44 45 77 4d 54 41 77 4d 54 41 67 4d 44 41 78 4d 44 45 78 4d 44 45 67 4d 44 45 77 4d 54 41 78 4d 54 41 67 4d 44 45 77 4d 44 41 77 4d 54 41 67 4d 44 45 77 4d 54 45 77 4d 44 45 67 4d 44 45 77 4d 44 41 77 4d 44 45 67 4d 44 45 77 4d 54 45 77 4d 54 41 3d’;

The "HEX / 64" is a hint that the next part of the code was converted into Hexadecimal and then Base 64 encoded again.

You end up with:
Binary = 01000100 01100101 01110000 01101111 01101110 01101001 01100001 00111010 00100000 01001101 00111000 01000110 00110010 00110010 00101101 01000111 01000010 00110100 00110100 01010010 00101101 01010110 01000010 01011001 01000001 01011010

That binary code then says "Deponia: M8F22-GB44R-VBYAZ"
