Throughout this weekend, you can try out Wild Terra free of charge. The event ends on Sunday morning, so it's a great time to head into the game. If you do, and if you choose to purchase the game, you can do so for $5 and all of your progress will be saved.
Wild Terra has recently been patched to bring some new features on board as well as to improve others. The most recent patch saw the addition of treasure maps and improvements to other systems including food effects, belts, skull crushing and more.
You can check out the Wild Terra Steam page to learn more.
