Ok, the game is almost over... Killer attacked, and i lost 5 cities so far - two of them very important one. I expect to lose 4 more (all important cities) in the next few rounds. My defenses are too weak against Berserkers. Killer had so far no losses at all through my defenses. All in all i managed to kill three Berserkers.
Thanks for reading the spoiler,
i hope you enjoyed your stay!
