Awakening of Evil

Good day. I downloaded, installed, and started playing. Difficulty level: Recruit. After only one in-game day, before I even reach the first chest, a creature emerges from a portal behind me with 7,000 dragons and 50,000 other monsters, and it kills me.

Regarding the last two comments – it seems that the map script is breaking at the very beginning of the game. Either the game version is not 3.1, or there is interference from third-party mods. Usually, reinstalling the game with the correct version helps.
