The online browser game does not require any download, plugin or add-on. In addition the 2D fantasy RPG stein.world is theoretically capable of running on any device or smartphone that can run a modern internet browser. That and much more awaits players within stein.world, while they’re on their epic quest to recover their lost family heirloom: the eponymous family beer stein. There is no strict class system within the game the items themselves dictate the play style. Stein.world offers a wide range of different types of items, so players can customize their character and classes to their liking. They can trade with each other, chat or unite in a group of up to five people to face the numerous threats of the dungeons & wave dungeons together. They are able to learn various professions like mining, herbalism or tailoring in order to craft epic pieces of equipment and consumables. The player can embark on numerous adventures and fight a variety of different enemies and monsters. What originally started as a small and fun hobby project and exercise in HTML5 coding has slowly evolved into a popular full blown F2P retro MMORPG experience.
