Q. How do I end the game?

A. There are five different ways.

• Death - Very typical ending for IVAN (as the title itself suggests). Simply, get killed by something, like monsters or land mines, but not limited to those...
• Freedom - Slay Elpuri and give its head to Petrus
• Knighthood - Can be achieved by giving Petrus the Shirt of the Golden Eagle
• Avatar of Chaos - Kill Petrus and take his left nut out of town. Mortifer takes you in personally
• High Priest - Kill Petrus, become Valpurus's champion and sit on the golden throne wearing the Shirt of the Golden Eagle
