Questions
- Why is my Alliance Tower Defense code not working?
- Copy the code exactly as shown, with no spaces before or after — codes are case-sensitive. If it is still rejected, you have either used it on that account already or it has moved to the expired list.
- How often do new codes come out?
- MrUpTime's Games drops codes around updates and player milestones — the 10M code marked the 10 million visits milestone, and the Halloween code landed with the October event. New codes usually appear on the game's Roblox page and the official Discord first.
- What are coins used for?
- Coins buy summons. Each summon roll gives a random unit, so code coins go straight into more rolls on the banner.
