Energy is very important in Wild Beyond. The more Energy you have, the more units you can play on the field. Make sure to build power plants as often as you can so you can earn more energy faster! Drag the power plant on the bottom-left corner to one of the three crystal clusters on your side of the battlefield. There is one located at the top and two at the bottom. Be careful though, if your opponent breaks through your barriers, they can destroy the power plants. If your strategy revolves around being more aggressive, you can instead take the power plants in the middle of the field simply by playing units and letting them move across the middle. As long as you have units controlling more than your half of the battlefield, you'll earn the bonus energy regeneration from these power plants as well.
