Conclusion:

I made longer than 1 hour in this map , inside castle, it was impossible to loose.... we stand 4 all together and defended doors. Two tanks came every few mins and we killed them easyly. Love this map ! Some dedicated servers already has it, and a lot of people has it, so you always find a mates to play online. Love this map !!! Must have !
