What Should You Do First?

When you are just starting Roblox Universal Tower Defense Z, your first few hours are the most important for making good progress. Firstly, you should focus on getting the best units and building a strong foundation. So, below are the most important things that you should prioritize:

  • Redeem Your Beginner Codes: This should be your first priority. As a beginner, you have a special chance to obtain useful units through beginner codes. These permanent beginner codes unlock strong starting units like Kimpachi (a versatile damage dealer) and Fern (a reliable supporter). So, this is the best way to start your adventure. Make sure to redeem them as soon as possible.
  • Complete the Tutorial and Early Story Stages: Play the first few easy Story Mode missions. This will teach you the basic gameplay mechanics while rewarding you with Gems, Player EXP, and your first units.
  • Claim Free Rewards: Check the Achievements, Unit Index (talk to the NPC outside the summon area), Level Milestones, Daily Quests, and the Battle Pass. These provide easy Gems, rerolls, and upgrade materials without requiring much effort.
  • Build Your First Team: Equip your starter units and head back into Story Mode on Easy difficulty. Focus on clearing stages and collecting more units to build your first reliable team.
