FAQ
How do I get more Coins?
Coins are earned by heroes killing creeps, earning Gold Stars (600 Coins per star), completing achievements, finishing challenges, or watching ads for free Coins.
What is Energy and how do I get it?
Energy is used to build towers and defenses. You start levels with some energy, gain more by killing Alien Creeps (amount varies by creep type), or earn extra by calling waves early.
What are Events and how do they work?
Events are monthly missions where you fight special “Covert Ops” enemies using Code Keys. Killing more special creeps earns better rewards, with Gold Mods available for full event completion.
What are Tower Mods?
Tower Mods combine Terran and Alien tech to boost stats like Range, Damage, or Turn Speed. Iron, Bronze, and Silver tiers improve stats, while Gold Mods add special abilities like extra infantry or reduced build costs. Earn them through event rewards.
What are the different types of Challenges?
Challenges unlock after level 9 and include Rush (1 life, unknown waves), Survival (3 lives, time-limited), Max Towers (3 lives, limited active towers), and SOS (5 lives, no energy from kills, pre-built towers).
Why can’t I access the final mission of the Nightmare event?
Nightmare event missions unlock daily from Friday to Sunday. If the final mission isn’t accessible, ensure you’re playing on the correct day or check for technical issues via support.
