MY EXPERIENCE:

so I study here at TUPManila,Phillippines and I play in a nearby computer Cafe. It is an automated server.
Attendants (non computer-literates) are not checking that well for computers are shutting down when your prepaid payment is over.
Then one day, they forgot to give my change, which I forgot too. It is worth us$1.00 but I cant forgive them for blaming me that its my fault so I ought to make revenge.
about 2 weeks later of finding a way to revenge I found my first way of free playing in that damn cafe

SINGLE PLAYER DUPE
I log-in then when before the last penny run out I disconnected the LAN hahaha it's so fun thinking im getting close to get my lost change.

to do this:
1.mouse 2 on the icon with 2 computers (Local Area Network CONNECTION)
2. Click on Disable
3. HAVE fun be careful XD


you can only play single player games in this dupe
