Alliance Tower Defense summons: coins, units and titans
Summoning is how you get units in Alliance Tower Defense. You earn coins by playing matches, spend those coins on a summon, and receive a unit to equip on your team. The official thumbnail promotes summoning titans, large units like the dark figure with a glowing blue core shown below.
Coins
Coins are the only currency the description names. They come from matches. The listing does not give summon prices, drop rates or rarity tiers, and this guide will not guess at odds.
Equipping a team
Summoned units are equipped to your team before a match. The number of team slots and whether units can be upgraded or merged are not published.
Titans
The official thumbnail's headline is Summon Titans. The game icon shows units with speaker and camera heads in green light. Which units are titans, and how titans differ from other units, has not been described in text by the developer.
Game passes
The public Roblox API returned no game pass list when this page was written, so paid boosts are not covered here.
