How to redeem

Universal Tower Defense codes will unlock Gems and Trait Rerolls much faster than you'd do so in-game, letting you focus on actually playing rather than grinding. Since you need Gems to unlock new units to take to battle, getting them as quickly as possible will help you breeze through combat, and with Trait Rerolls, you'll be able to equip your units with powerful and useful perks too which is bound to make any fights that little bit easier.

When she’s not raising a dodo army in Ark: Survival Evolved or taking huge losses in Tekken, you’ll find her helplessly trawling the internet for the next best birdwatching game because who wants to step outside and experience the real thing when you can so easily do it from the comfort of your living room. Right?
