Message from the developer: It’s a pleasure to introduce Orb Master here. Let's talk about who we are first. We are a very young game development team like a baby in this industry. We hope that Orb Master and us can grow into capable adults together. We strive to be creative and unique. We always try to make a unique game. That’s how Orb Master is made. We have designed 44 Orbs with different special skills. By forming different lineups, you can have different strategies. -We hope that players will feel relaxed when playing this game after working and studying. So we make it easy to get the Orbs. Even the newbie can easily obtain Legendary Orbs by playing Co-op with experienced players. -We think that traditional tower defense game is boring because there is no PVP mode You can defeat the other players in a game within 3 minutes. Also, you can defeat the monsters with friends in Co-op mode. -We want to have flexible strategies in different modes There are PVP mode, Co-op mode, Grand Prix, and Infinite Firepower, etc. Different strategies and lineups for different modes. We still have many ideas to be developed for this game. Stay tuned. What’s more, we think your feedback is important too. The player and developer can make a better game together. We are looking forward to your contribution. Every Orb is weak alone, but when they stand together, they are invincible. Have fun!
