Wilds.io is a very fun browser-based multiplayer arena RPG game. What this means is that you get to play against other players in real time straight from your internet browser, such as Chrome. And since it is an RPG genre game, you can improve skills, purchase new equipment and level up.
You can improve your skills and level up by earning experience points or XP. XP is gained from beating other players, monsters or the in-game bots. As you also beat these enemies, you can earn money to purchase better items and equipment. And you have to level up wisely and purchase better equipment if you do not want to get beaten by the other players.
This is because it would mean that you would have to start over from level one again. So level up and customize your player character in order to be the best hunter in this massively enjoyable RPG game.
