===============
1) Introduction
===============

Battle Carry is a tank war game developed by AFSL Games
(http://www.afslgames.com) and released in October 2005.

2) Bug
======

A packet bigger than 8192 bytes causes a socket error in the Python
code used to handle the server which immediately terminates the socket
and interrupts the listening on the UDP port where has been received
the packet.

No fix.
Developers have been contacted but after the only mail I received I
have no longer heard them so I don't know when and if a patch will be
released.
