How about adding a nice menu icon and desktop file? Then it would be easy to create a nice Debian package. Also fix the file permissions. Usally every file should have 644, like
find zb_beta_v10/ -type f -exec chmod -v 644 {} \;
chmod +x zb_beta_v10/tank.x86 zb_beta_v10/start_client.sh
Then the permissions are correct. Maybe also update the start script:
#!/bin/sh
cd "$(dirname $0)"
export LD_LIBRARY_PATH=./shared_libs
./tank.x86
Then you can execute it anywhere. And when you did that you could easyly create a debian package. If you need assistance just ask.
