Marco, the guy who quietly worked himself into the office all day, and then it happened that is really terrible. He saw a lot of different monsters, among which were basically zombies. But Marco was not taken aback, and ran to his boss's office, took his sword, which he kept as a relic, and started killing all the monsters around. Today you would need on every level of a certain amount of monsters to kill, or perform other tasks. So you can improve skills marco, and buy him a gun. Good luck to you and wish to survive!
