This is a scenario that uses the same victory conditions as the "Regicide" gamemode from AoE 2. The goal is to kill the enemies King (in this version it's Arkantos). Thus it is your goal to protect your own King from all harm. It can be played with up to 4 players, I included a 1v1 and 1v1v1v1 version (You can also set up teams, for example: 2v2.
How to set it up:
Fill the first 4 player spots with human players, make the fifth player a AI. You can set up teams as you like, the fifth player will always be allied with the other 4. You could also use AI opponents, however they do not protect Arkantos.
In the 1v1 version you have to set the first two players to humans and set the last 3 to AIs. There may be 5 players in total but only 2 (Blue and Red) will be actually able to play.
