About ERZ Online
ERZ Online is a 2D mining MMO set on a cluster of asteroids. You control a team of mining bots, dig for minerals, trade them with other players and use the profits to grow a bigger, more automated operation.
The core loop is straightforward. Your bots mine resources and bring them back to base. You sell what they find on the market or spend it on research. Research unlocks better tools, new bot parts and buildings. Upgraded bots dig faster and reach deeper, richer deposits, and the cycle starts again on a larger scale.
Automation is a big part of the game. Bots can run programs that you put together in a visual editor from simple blocks such as movement, scanning and conditions. No coding knowledge is needed. Once a program works, your bots mine on their own and you can focus on trading, research or expanding your base.
As you progress, you build infrastructure directly in the rock, from stations that recharge your bots to machines that reveal hidden deposits.
The economy is player-driven. There are no fixed prices: players place buy and sell orders, and the value of each resource depends on supply and demand.
Some asteroids have PvP enabled. There you can run into other players' bots and decide whether to cooperate or fight. Hostile creatures are a threat as well.
ERZ Online is in active development, and player feedback shapes future updates.
