If you have grown bored of single-player within Medieval Engineers the Multi-player has plenty to offer.
You can step into a whole new realm of pure creativity or take on the challenge of survival. While either tackling these obstacles either cooperatively with others or head face first into competitive and wage war against other players.
All these possibilities and more await you in multiplayer, while still having the ability to totally customize your gameplay experience to your own personal desires. With the options to player offline, private, friends only, and public games await you.
